The Blues frontman has already notched up 13 goals so far this season, including an impressive nine in his last nine outings.
“He’s scored a lot of goals throughout his career, but he's certainly in a great run of form at the moment," said the Blues boss.
"The more clean sheets we keep at the other end, when we’ve got a player in this form the better.
"He can get you a goal out of nothing. Whether the team is playing well, or he personally is playing well, you know if he gets half a chance that nine times out of ten he’ll score and that gets you the 1-0 win.
"As long as he keeps playing like that we give ourselves a chance, so we’ve got to keep giving him chances."
