London: Southampton manager Ronald Koeman on Thursday backed Oriol Romeu to prove his worth in the Premier League after the Spanish midfielder signed from Chelsea on a three-year contract.
Romeu, 23, completed a £5 million ($7.8 million, seven million euros) move late on Wednesday after spending the last two seasons away from Chelsea at Valencia and Stuttgart.
Romeu joined Chelsea from Barcelona in 2011, but a serious knee injury sustained in December 2012 saw him lose his place in the first-team hierarchy.
However, Koeman is convinced he has what it takes to thrive in the English top flight, telling a press conference: "He`s a very good player.
"(He is) 23 years old, played already in the Premier League, had a good season in Stuttgart last year and he makes the team stronger.
"It`s not easy to be a player in the first XI of Chelsea because they have so many good players and for young players it`s difficult. It`s always up to the manager, the confidence of the player.
"I think it`s the right moment for the player to make this move to Southampton because he will play more for Southampton than for Chelsea."
Koeman missed Southampton`s 2-2 draw at Newcastle United last weekend after undergoing surgery on his Achilles tendon, but will return for Saturday`s home game with Everton.
