Harry Redknapp was full of praise for Peter Crouch's performance off the bench in Saturday's win against Birmingham.
The striker was thrown into the action early in the second half at the Lane following an injury to Luka Modric.
'Crouchy' created havoc for the next 35 minutes as we grabbed a last-gasp winner to make it four in four in the Premier League.
He was unlucky not to score on three occasions - Joe Hart saved one header, Lee Carsley cleared another off the line, a third hit the crossbar - before finally opening the scoring with a precise, looping header into the corner after 72 minutes.
City levelled just four minutes later but we found a winner in the fourth minute of injury time when Aaron Lennon fired home.
"Crouchy was different class when he came on," said Harry.
"He won every ball that went into the box and could have scored three or four.
"When a game needs changing he can come on and do that, even if he's coming off the bench he can come on and completely change the way you play. If you can't play through teams you can go long to him and he gives you a different dimension. He was outstanding."
