British star Luol Deng has agreed a new six-year deal with the Chicago Bulls.

The 23-year-old's big-money deal is worth a guaranteed $71million (approx £36m), with incentives taking its possible worth to $80m (£40m).

Deng had rejected a five-year deal but his impressive displays in the team's miserable 2007-08 season ensured they were keen to find a way to keep him.

Deng, who was born in Sudan but lived in Britain from the age of nine to 15, when he moved to America, will be leading Britain's bid to qualify for the 2012 London Olympics.
