Former Nigerian international and MLS veteran Michael Emenalo, who played college soccer at Boston University and for the San Jose Clash, has been appointed first-team assistant coach for Chelsea.

Emenalo, 45, has joined the club in 2007 under the regime of manager Arvam Grant and has formed a good liaison with current manager Carlo Ancelotti. "Michael Emenalo is doing a fantastic job as head opposition scout and he is already working very close to me," Ancelotti said.

Emenalo played for Nigeria at the 1994 World Cup and for San Jose made 56 regular-season appearances in 1996 and 1997. He played in Spain and Israel before retiring in 2000.

Ray Wilkins, a former Chelsea player, left the club last week after reportedly after being told his contract would not be renewed.
