This may be the night that constituted the true start of André Villas-Boas’s reign as manager. A resounding victory on an occasion when Didier Drogba, with two goals, was irresistible ushered Chelsea into the knockout phase of the Champions League as group winners. Defending and fine goalkeeping by Petr Cech were also crucial, but the whole team had tenacity whenever technique wobbled.

The match may have looked as if it could be overwhelmed by anxiety, but the teams behaved initially as if they would relieve the tension by launching themselves into attacks. Chelsea were ahead after three minutes but even that goal felt delayed since Diego Alves had made a save from Raul Meireles shortly beforehand. It was Drogba who struck for the hosts as he converted a cut-back from Juan Mata with a left-footed finish after eluding the right-back Antonio Barragan.

Both sides produced vivacious attacks, but Chelsea were the more precise when opportunity arose. With 22 minutes gone, Drogba assumed the role of orchestrator as he freed Ramires on the left to go clear of the centre-half Victor Ruiz and extend the advantage with a low shot. The score spoke more of ruthlessness than overwhelming superiority in that part of the evening and Valencia could also have made an impact then.

There was no lack of verve in Unai Emery’s line-up. Cech, for instance, had needed to stretch to divert a long-range shot from David Albelda in the 10th minute that could easily have tied the score at 1-1. Chelsea, though, had made an impact by then and debate died at that stage over the decision merely to have Frank Lampard on the bench.

The midfielder had a disgruntled air when he was taken off during the weekend victory at Newcastle United so a further demotion to substitute on a night such as this must have left him dismayed. He has been absent from the first XI on other occasions in this campaign, but this exclusion had resonance. The early phase of this contest seemed like vindication for the manager Villas-Boas.

If the Portuguese had judged just one veteran, he seemed to have been astute then in opting for Drogba. More generally, altering and rejuvenating the line-up cannot be a mere aspiration. It is a task that Villas-Boas is obliged to undertake. There must have been feeling, too, that there needed to be unwavering energy if Valencia were to be overcome. Emery has an appealing side and it seemed in their nature to mount attacks, even if Chelsea’s early impact had left them with scant choice in the matter.

Daniel Sturridge had a chance to add a third, but the attempt was turned away by the goalkeeper Alves in the 28th minute. Chelsea had impact in the first half that is not demanded regularly of the Premier League’s representatives. The group phase of the tournament has often been akin to a waiting room for the English teams.

They fidget and get a little bored but know virtually for certain that their journey will begin in earnest soon enough as they stride into the last 16. This season has been different for everyone other than Arsenal. Given Chelsea’s expectations, there was almost an indignity in hearing people discuss the arithmetical calculations that could have been called for if the sides went on being so difficult to disentangle from one another.

It would have been foolish of Chelsea to assume that they would defeat the team from La Liga when Villas-Boas’s side had lost three times at home in all competitions since late October. Valencia, who had won seven of their last eight games in all competitions, must have sensed an opportunity but Chelsea altered that mood with that first-half impact.

The contest did not retain its full intensity immediately following the interval. Chelsea may have been told to take care, but it was also true that Valencia had shed inhibitions by then. There was nothing left to fear when they were already in such a plight.

Chelsea concentrated mainly on discipline and concentration. Valencia therefore had more of the action and there was animation among the visiting supporters. They would have been conscious, too, of the difference one goal would make.

Chelsea, however, appeared orderly and they also understood that they were bound to find opportunities on the counter. Ramires and Sturridge did break away but then bungled the move. They could have been punished for such laxity but Cech made an excellent leap to turn it away for a corner.

The Stamford Bridge side do not resemble the impregnable line-up of days gone by and it was no mystery that Villas-Boas should resort to conservatism when replacing Ramires with the specialist holding midfielder Mikel John Obi. There was a sense of occasion to this match once again, but not of the sort that the regulars could savour.

In practice, Chelsea were in a strong position, but they do not have the aura of invincibility that appeared to cloak them in years gone by. Drogba would have been adored all the more if he had lifted the tension in the 73rd minute, as he thundered away from Adil Rami, but the ensuing drive was miscued. Even so, Drogba was not to be denied three minutes later as he slipped a shot home neatly to release all tension from Stamford Bridge.

Today’s piffle nominates young Werther here

The perennial sight of the Mill, head tilted backwards and freshly tweezered snout cocked at the jauntiest of angles in pursuit of the newest gossip – to the exclusion of everything else, be it a death in the family, a new series of Eldorado or a two-for-one offer on 44% ABV Liquid Happiness in Morrisons – might suggest a cold, emotionless entity; a punter-gatherer devoid of flesh, blood and a subscription to Time Out. But the humble, oh-so-human Mill has simple dreams, fantasies, desires. To feel the soft, tender kiss of a silky thong 24 hours a day; for society to soften its stance towards Vicks Inhaler addicts so that we no longer have to skulk around inhaling guiltily the moment every back is turned; to hear the internal monologue of Dean Windass, particularly when he is on Sky’s Soccer Saturday and struggling with such polysyllables as ‘Jeff’; and to see Andrés Iniesta, Xavi and Cesc Fábregas redefine football by playing together in the same club side.

One of those dreams moved closer when Cadena SER radio reported that Fábregas has reached a verbal agreement to rejoin Barcelona in the summer. “Several meetings have taken place and, following those meetings, Cesc told Barça that he wanted to rejoin them from next season,” sniffed the Mill’s Spanish source, Señor Scandalmonger. Obviously there is still the small matter of Arsenal agreeing a fee, not to mention Pep Guardiola accommodating all three into a workable system, but the Mill is pretty excited nonetheless.

So, it would seem, is Bordeaux’s Moroccan centre-forward Marouane Chamakh, who has apparently agreed a pre-contract with Arsenal worth £50,000 a week over five years. Chamakh will join Arsenal at precisely the moment William Gallas leaves. Gallas, aged 457,195,525,569,123,564, is emitting warm vapour from most orifices because Arsène Wenger will only offer him a new one-year contract. Gallas wants two.

Now, we’re sure the Daily Star’s Danny Fullbrook is a good bloke. Salt of the earth is Dan. An ordinary Joe. A man you can trust. A diamond. But if Dan’s exclusive today, that Dani Alves will leave Barcelona to join either Chelsea or Manchester City for £30m in the summer, comes true, we’ll happily – nay, lovingly – hang a pair of Dan’s used ones on our wall for a whole year.

In an unrelated development for which we can’t manufacture even a contrived segue, never mind a relatively smooth one, Lord Ferg’s policy of buying foetuses and geriatricos will continue when he pilfers two 15-year-olds, Valerio Verre and Filippo Cipriani, from under Roma’s nose.

The ceaselessly warm relationship between Roberto Martínez and Steve Bruce will again be in evidence in the summer when the two adorn blood-flow-restricting lycra and wrestle – three falls and a submission – on a pleasantly scented blue mat. To the victor, Cruz Azul’s Paraguayan midfielder Cristian Riveros; to the loser, an erotic frisson that dare not speak its name.

And, finally, when the Mill asked 100 punters to name a Bolton-born brainbox who is currently in the doghouse after failing to keep it in his trouser pocket, they all named Vernon Kay. Our survey says: you numpty.
