"Defoe and Baros played well together against Chelsea and will probably start together against Bolton on Saturday," Nugent told the club's official website.
"I need to impress in training if I want to get another chance.
"I've played with Jermain before when we met up with England. I came on for about 20 minutes and robbed his goal!
"He's a fantastic player and he deserves his latest England call-up.
"Milan Baros is another good signing, he's scored a few goals in The Premier League before.
"[Lassana] Diarra is something special, he looks class in training and has done well in every game that he's played."
