The 19 year old right back has played just 18 times for Southampton but is seen as an enormous prospect that Arsene Wenger has been following for some time.
The Gunners have confirmed on their official website that the Englishman has joined the North London club on a long term contract for an undisclosed fee, believed to be in the region of £16 million including add-ons.
Speaking on the signing, Wenger said:
We are very pleased that Calum has agreed to join us. The way he adapted to the Premier League last season with Southampton at a young age shows that he has tremendous quality. He has a lot of the attributes that we look for in a young player and I am sure that he will do well with us.
I am so happy to be signing for Arsenal. They are a team I have much admired for their playing style, and a team who have been one of the top sides in Europe for many years. I’m looking forward to joining up with my new team-mates today and beginning preparation for the season ahead.
I would like to take this opportunity to say thank you to everyone at Southampton FC for everything they have done for me and for making this move possible.
The youngster is the second right-back the Gunners have bought this season, having already signed the France right-back Mathieu Debuchy from Newcastle to replace Bacary Sagna, who has joined Manchester City on a Bosman transfer.
He is a versatile defender, who can get forward when necessary, who may provide cover at centre half or develop as a defensive midfielder – both are positions he has occupied in the past. He will suit Arsenal’s style of play and provide some much needed strength and depth at the back.
His signing will put the short-term future of Carl Jenkinson into jeopardy, but it remains to be seen whether Wenger plans to keep both Chambers and Jenkinson to use both as cover for right-back and centre-back. Jenkinson has been tipped for loan move away which could be ideal for the 22-year-old’s development.
What a summer of signings it has been so far! Four senior signings before August, who would have thought?
Welcome to the club Chambers!
