Alex McLeish reckons Birmingham's game against Tottenham is the biggest of his managerial career.
The relegation-threatened Blues will travel down to White Hart Lane on Sunday in what is a must-win game for them.
They are currently 17th in the table on 39 points and are one of five teams that go into the final day of the campaign battling to avoid the drop.
It comes just three months after Birmingham shocked Arsenal in the Carling Cup final to claim their first trophy in decades.
McLeish is in no doubt about the task that he faces, but is confident he will achieve it, saying: "It's hypothetical stuff. I'm not going to get involved in ifs and buts (about my future).
"But I do know it is probably the biggest game of my career.
"It is certainly the biggest of my managerial career - so bring it on.
"I believe we will stay up. We have to try and play to the strengths the players possess.
"We know opening up against a Spurs team could be deadly.
"We've got our own strategy and we have to try and be good on the day to get a positive result at White Hart Lane."
What will the outcome be?
