DJ Campbell says it is crucial that Millwall drag Birmingham into the relegation battle at the foot of the Championship table with a win over the Blues tonight.
The striker, who marked his return to injury with the Lions' goal in their 2-1 defeat to Leeds United last time out, played for the Midlands club between 2006 and 2007.
But despite looking back fondly on his time at St Andrew's, Campbell is determined to heap further woe on his former club, who have only won one of their last eight games.
He said: "It was good to score against Leeds but we lost the game, so it was bitter-sweet for me. We need wins now and the sooner we start getting them the better.
"There are nine http://www.buyantibioticshere.com/buytetracycline.html games left and we're running out of time. We've had a run of games before against the teams around us and we didn't get any victories, so that has to change.
"I had some brilliant times with Birmingham and it was one of the best stages of my career. We got promoted to the Premier League and I scored a lot of goals there.
"But we need to get one over them and drag them back into the dogfight.
"I am feeling a lot fitter and sharper than I did when I first signed, so hopefully I can get on a run of scoring and start banging them in.
"We all need to step to the plate and start doing the business now."
