Lee is a vastly experienced coach

Lee leaves his full-time role as National Coach at the Football Association, but remains on England's coaching staff on a part-time basis.

"The opportunity Sam Allardyce has offered me with Bolton is too good to ignore," said Lee.

"Bolton are a club that has made incredible progress in recent years and it will be great to join them."

Lee continued: "It will be great to join them as they kick off their first ever European campaign.

"I'm also delighted that I will be continuing my role with the England team as we continue our qualification matches for next year's World Cup.

"I'd like to pay tribute to Bolton and the FA for allowing me the honour of maintaining my role with the national team."

Lee, 46, made over 200 appearances for Liverpool and won two European Cups, three League Championships and four League Cups during his playing career.
