London - Petr Cech's stunning form with Arsenal appears to have gone unnoticed by his sponsors Adidas, who delivered a pair of new goalkeeper gloves to the training ground of his former club Chelsea.
The Czech Republic international, 33, spent 11 very successful years with Chelsea, notably winning four Premier League titles and the 2012 Champions League, before crossing London to join Arsenal during the close season.
He was expecting a new pair of gloves to be delivered ahead of Sunday's match between the clubs at the Emirates Stadium, only for Chelsea to inform him that they had been sent to their Cobham training base in error.
Asked on Thursday if he would check Cech's new gloves for signs of skulduggery, Arsenal manager Arsene Wenger replied: "He's big enough to check his own gloves.
"I think he has enough gloves. These kind of mistakes can happen. I consider him now as a real Arsenal player who looks to me as if he's been here forever.
"He has adapted so well and integrated to team spirit. This kind of incident is an accident."
Arsenal are currently top of the table on goal difference from Leicester City, with defending champions Chelsea 19 points off the pace in 14th place.
