Petr Cech
Arsenal are expected to announce the signing of Petr Cech soonReuters

Arsenal are on the verge of completing the transfer of Petr Cech from Chelsea with the goalkeeper undergoing a medical at London Colney today.

The Chelsea goalkeeper agreed on personal terms with Arsenal a while back, believed to be around £100,000 a week, while the transfer fee has been pegged at £11 million.

BBC Sport journalist David Ornstein broke the news of Cech's medical on Twitter.

"Chelsea gk Petr Cech will undergo a medical today ahead of completing his proposed move to Arsenal. Fee & personal terms agreed #AFC #CFC," Ornstein wrote.

Sky Sports had reported yesterday that Cech's medical might happen only next week, but it looks like the signing has been fast-tracked.

Cech to Arsenal has been one of the stories of the transfer season so far, and while Chelsea manager Jose Mourinho is not too happy about the move, Roman Abramovich has stood true to his word of allowing the 33-year-old to choose his next club as a thank you for the 11 years of outstanding service.

Arsenal will be considerably strengthened by the arrival of Cech, and the experienced goalkeeper's presence will go a long way towards confirming Arsene Wenger's men as one of the title contenders for next season.

John Terry, the Chelsea captain, certainly feels Cech will add some serious quality to the Arsenal team next season.

"If they do get him, he will strengthen them for sure," Terry told TalkSport on Monday. "He will save them 12 or 15 points a season. Petr was an unbelievable professional last year. When you get left out of the team it can be hard to accept but when he came in he was exceptional.

"He deserves a lot of credit for that. We understand he wants to play first-team football but nobody wants to see him leave the club. He's going to be sorely missed and will improve any side he goes to."

Wenger has also been linked with a holding midfielder, while the Arsenal manager is also expected to sign a striker before the close of the transfer window.
