Lee has completed his first full week of training with West Ham, and Michael says:
"He is a quality player and he showed on Saturday what a great player he is - hopefully he will bring some goals to the side, and other good things.
"When someone like that comes into the team you are going to get a lift, and we are delighted he is here."
As for the trip to Highbury in the light of Lee's debut, a 2-2 draw with Newcastle, he says:
"It was a disappointment because it is points that count, and, especially after the way we played, I thought we deserved much better.
"It just seems to happen when you are at the bottom that people score great goals, as Jenas did, and give you a kick in the teeth.
"They say you make your own luck, though, and we are going to have to do that.
"We have to bounce back against Arsenal - we played well enough against Newcastle, we defended well, and we are scoring goals.
"You have to play them some time so we might as well go there and get three points this weekend.
"We have shown against the top teams we can be better than them so we go there with confidence and hopes for a win."
And Arsenal as champions-elect?
"It is tight but I am not too bothered; we are concentrating on ourselves," he says.
Many feel that if West Ham had beaten Arsenal at home in August the Upton Park problems of this season would have dissipated, but he insists:
"The lads aren't too fussed about the record; three points are three points wherever you get them.
"It is nice to be off the bottom of the league but we want to be fourth or fifth bottom."
