"I'm delighted about the prospect of being Bolton manager. It is a great legacy that Sam has left and it is my job now to carry that forward," said Lee at his unveiling.
"I am very proud to be sat here in front of everybody as the new manager of Bolton Wanderers.
"The education I've gained from working with Sam Allardyce has been immense.
"I have to continue what Sam has started, that's first and foremost, and then re-evaluate it after that.
"It certainly is a healthy position that Bolton are in, we're now contesting for a place in Europe.
"The main thing for us is to keep the players stable and to make sure that we get the result we firmly feel deserve after all the hard work we've done this season."
