Chelsea sign young Czech defender Tomas Kalas from Olomouc

• Fee for centre-half could reportedly reach £5.2m
• Defender to be loaned back to Czech club next season

Chelsea have signed the 17-year-old Czech defender Tomas Kalas. Chelsea and the player’s agency, Sport Invest Group, said Kalas will stay with his Czech club, Olomouc, on loan next season before moving to Stamford Bridge.

Other clubs interested in the player included Arsenal, Milan, Bayer Leverkusen and Hoffenheim. Details of the contract have not been released but Czech media have reported that Olomouc could receive 160m koruna (£5.2m).

The Chelsea website said of the player: “Very athletic and quick, he is a very good one-on-one defender and comfortable on the ball. We feel there is a lot of potential in the player, and we feel at the minute it is the right time to get him, but it would be good for him to stay there and get first-team experience, and we look forward to him joining us next year.

“Obviously we will stay in touch and he will come across here when appropriate. He is a right-sided centre-half who can play right-back.”

John Terry lays into Wembley pitch after Chelsea win FA Cup final

• Defender says pitch was ‘worst we’ve played on all year’
• Chelsea captain also pays tribute to team’s ‘determination’

John Terry said it was a “special” feeling to help Chelsea seal their first league and FA Cup double by beating Portsmouth 1-0 at Wembley. But even as his team’s celebrations were getting under way the defender was quick to add his voice to those condemning the national stadium’s playing surface.

“The pitch ruined the final,” said Terry. “It’s probably the worst pitch we’ve played on all year. It was not good enough for a Wembley pitch. The FA have to decide if this is a football pitch or events stadium.”

Even if he felt the final had been compromised, however, Terry described the achievement of winning the double as “unbelievable”. “It’s never been done in the club’s history and to do it with this group of players feels so special,” he said. “I thought our luck was out, but what a great free-kick from Didier.

“It was one of those days, but we came strong and full credit to Didier. The reason why we are top of the league and won the FA Cup is that we are the best team and we have great determination.”

For all that Chelsea outplayed Portsmouth, hitting the woodwork five times during the game, the south-coast club had an opportunity to take the lead when Juliano Belletti brought down Aruna Dindane in the area. Petr Cech saved Kevin-Prince Boateng’s spot-kick, but suggested afterwards he had been “lucky” after the Portsmouth midfielder scuffed his shot.

“I knew what the choices were and, from the body language when he ran towards me, I chose that side – but I was lucky to get there,” he said.

The Czech international added that the players were desperate to write their names in the club’s history, which he felt may have played a part in them missing so many chances before Drogba finally made the breakthrough.

“I’m speechless because during the game there were a lot of emotions,” he said. “We wanted to be the first team at Chelsea to win the double – and we also defended the FA Cup, which is an achievement as well.

“We kept missing and missing, and it looked like it was not going to be our day, but to make two crucial saves I am delighted.”

Drogba admitted it was hard to come back down to earth after sealing the Premier League title last weekend with an 8-0 thrashing of Wigan.

“It was difficult to come back and stay focused [after] we celebrated the title,” he said. “It was difficult again against a very good Portsmouth team. You start to feel that you won’t score, but if you manage to create chances in the first half it means, in the second, you will have some.”

Of his free-kick goal, Drogba added: “I saw a little gap, not a big space, because the wall was in its position. I hit the post again, but it went in this time.”

Football transfer rumours – Pepe Reina to Chelsea? | John Ashdown

Chamakh to Arsenal | Man Utd £100m car boot sale | Sterling to Liverpool

Mondays are not usually a great day for the Mill. With (Pah!) match reports clogging up the day’s papers with news of things that have (Spit!) actually happened in the (Other Generic Noise of Digust!) real world, the tittle-tattle is something of a muddy puddle rather than the vast panoramic ocean of speculation that we know and love.

Today, though, is different. Today is a red letter day, particularly for those below the line. Break out the bunting, don that celebratory waistcoat and roll a keg of beer into the street because today, at last, Marouane Chamakh has signed for Arsenal. Well, nearly. Tabloid reports reckon the Bordeaux striker is finalising a four-year deal with the Gunners, but that the deal is effectively done.

Chamakh could be joined at the Emirates by West Brom midfielder Graham Dorrans after the Gunners joined the five-way tug of war for the player. Newcastle and Sunderland each have an arm, the Gunners and Manchester City have a leg, while Celtic are putting on rubber gloves and hoping he’s had a bath.

The Daily Mail reckons Birmingham manager Alex McLeish is to send scouts to watch Kris Boyd in action for Scotland against the Czech Republic at Hampden this week. They’ll compile a report on the player and then walk back to St Andrew’s in order to earn their orienteering badge.

Liverpool have secured a deal for 15-year-old QPR wonderkid Raheem Sterling. Rangers get £500,000 plus add-ons, while Sterling and his camp get £200,000 and a contract to 2014. Rafa Benítez is also keen on Lille defender and sometime Derby County mascot Adil Rami, and Rennes full-back Rod Fanni (insert your own joke here). Pepe Reina might not be at Anfield to greet them, though – he was yesterday linked with a £20m summer move to Chelsea.

Not to be outdone in the child-signing business, Barcelona have bagged ‘the Korean Messi’, 13-year-old Park Sheng-ho. Reports that the club are close to concluding a deal for ‘the toddling Kaka’ and ‘the foetal Pele’ have so far proved to be wide of the mark (but just give it time).

Manchester United will have a £100m car boot sale in the summer. Michael Owen, Nani, Gabriel Obertan and Owen Hargreaves are all lined-up on Sir Alex Ferguson’s trestle table, along with some albums on tape, a pack of playing cards with the seven of spades missing and a Power Rangers action figure with its head chewed off.

And free agent Salomon Olembe better get on his cape and out his pants on over his trousers because he’s the man Brian Laws wants to save Burnley’s season. The former Leeds, Wigan and £8m Marseille man could even play for the Clarets reserves this evening.
