Born in Arras, France, the left-sided 22-year-old is one of the most highly-rated full-backs in Le Championnat.
Sporting Director Damien Comolli said: Ã¢â‚¬Å“Benoit is a young, extremely talented left-back.
HeÃ¢â‚¬â„¢s versatile and can play in three positions Ã¢â‚¬â€œ left-back, on the left side of central midfield and left midfield. He will give Martin lots of flexibility on that flank.
Ã¢â‚¬Å“HeÃ¢â‚¬â„¢s regarded as one of the best prospects in French football and is an excellent signing for the Club.
Ã¢â‚¬Å“The player is ambitious and has always wanted to play in English football. He was consistent in his commitment to us in the negotiations we had with Lens despite a lot of interest from other clubs and Lens being reluctant to let him go.Ã¢â‚¬Â
Benoit featured in 34 of 38 league games, starting 33, as Lens finished fourth in Ligue One last season.
Kicking-off last season in the Inter Toto Cup on July 3, he played in all of LensÃ¢â‚¬â„¢ games as they won that tournament and therefore secured a place in the UEFA Cup. He then played in seven of eight UEFA Cup matches as Lens went out to Udinese in the last 32.
After breaking into the first team with three appearances in 2003-04, Benoit caught the eye with 29 starts in 2004-05.
The Club is delighted to announce that it has reached agreement with RC Lens for the transfer of Benoit Assou-Ekotto.
