Mauricio Pochettino suggests Fernando Torres is unhappy at Chelsea

Southampton manager Mauricio Pochettino has suggested that Fernando Torres's form has been affected due to his unhappiness at Chelsea.

The Spain international, who moved to Stamford Bridge from Liverpool for £50m in January 2011, has only managed to find the net seven times in the Premier League this season.

"I remember him being a quality player, full of strength and a player who knew which spaces to run into to create chances," the Daily Star quotes Pochettino as saying. "Sometimes it happens where a player is comfortable and feels happy at a certain club as he was at Atletico and at Liverpool.

"But when you leave that club and join a new team maybe you do not feel as comfortable and as happy and that can affect your performances. I do not know if Torres will leave Chelsea but what is clear is there is no doubting his quality."

Pochettino will lead his Saints side into a league encounter against the Blues at St Mary's tomorrow.
