Gaffers View: Southampton v Blues
The striker had been on the field for barely a minute before he scored against his former club to hand Blues another win.
McLeish said: 'Kevin is a fabulous striker and there is no-one better than him at scoring goals like that.
'He has the ability to score whenever he is on the pitch and you know that if he gets just one chance then he will bury it.
'I thought Southampton were the better side in the first half but we were much the better side in the second. Southampton deserved to go into the break 1-0 up but I am pleased with our performance in the second half.
'We created a lot of chances and I felt we fully deserved our victory and all three points and I am really pleased with the way we performed.'
