Sonko started his career in the academy at St Etienne

Reading defender Ibrahima Sonko has joined Premier League new boys Stoke City on a three-year deal for �2m.

The Senegalese centre-back joined the Royals from Brentford in 2004 and played a big part in their Championship-winning season in 2005/06.

The 27-year-old told BBC Radio Stoke: "I was really happy when my agent told me that Stoke were interested.

"Every player wants to play in the Premier League so when Stoke gave me the opportunity I couldn't say no."

The fee for the international could rise to �2.25m depending on appearances and the Potters' future success.

The centre-half was injured during their first Premier League campaign and was in and out of the side last season.

He was suspended for two weeks after a breach of club discipline in May and in June said he wanted to leave although he has started this season in the side.

"As much as I love Reading it was time for me to leave and join the big boys again," said Sonko.

"I already know some of the guys at Stoke so they should make me feel welcome straight away.

"Hopefully will all the new signings Stoke can enjoy a long time in the Premier League."

Sonko is currently Reading's top scorer after finding the net twice against Plymouth two weekends ago and then getting another goal before collecting a red card at Charlton last Saturday.
