Oppositions View: Kenny Jackett - Millwall
The Lions went down 4-1 at the Den and the Championship outfit found themselves three down by the break.
They were not helped in the second half by Steve Morrison who missed a penalty.
Jackett said: 'I'm disappointed with the result.
'I wanted to try and cause an upset today but I look back now and Birmingham were clinical. That made the difference.
'It was a 4-1 game if you put your chances away.
'Finishing is a big part of the game and obviously shouldn't be underestimated but Birmingham were clinical today.
'We started well, had a number of chances and put the pressure on them and we perhaps needed the first goal.
'But even then along the way we needed to score to build up momentum to bring the crowd into play.
'We couldn't do that even at the start of the second half where we did have a good spell with a number of chances and a penalty.'
He added: 'I do see it as a positive if a team creates chances, it means there is spirit in the side and it means you are two thirds of the way home.
'Obviously then you have to convert them but it is a positive if you can create a lot of chances in the game.'
