• Ajax beat Chelsea 3-1 in Amsterdam
• Ross Turnbull’s mistake gifts Ajax victory

A calamitous error by Ross Turnbull helped Martin Jol’s Ajax to a comfortable win over a young Chelsea side in their pre-season friendly fixture in Amsterdam.

Jol, who is to remain in Holland after his club refused to release him to take over as Fulham manager, would have been delighted by the positive start his side made against the Premier League champions and they were rewarded with an early goal.

The former Feyenoord youngster Jeffrey Bruma attempted to clear a cross in the box but his header struck Turnbull on the arm and flew into the net.

Daniel Sturridge then scored an excellent equaliser for Carlo Ancelotti’s side, who were again without their World Cup contingent. A loose ball broke to the England Under-21 international around 25

• Petr Cech has scan after run at Chelsea’s training ground
• Goalkeeper missed four weeks last season with muscle tear

Petr Cech has suffered an injury to his right calf in training and the Chelsea goalkeeper fears that the problem is a recurrence of the muscle tear that ruled him out for four weeks in the second half of last season.

Cech felt the twinge while on a routine run during training in Cobham today and he was immediately forced to withdraw. His lower right leg was placed in a protective boot and he now faces an anxious wait on the results of a scan.

The 28-year-old tore the muscle in his calf in last February’s Champions League last 16 first-leg tie against Internazionale in Milan and he missed the next five matches for his club, including the return fixture with Inter, which Chelsea lost to exit the competition.

Chelsea play the Community Shield at Wembley against Manchester United two weeks on Sunday, before opening the defence of their Premier League title the following weekend at home to West Bromwich Albion and, if Cech’s worst fears are realised, he would miss the beginning of the season.
