Robbie Keane will come up against a familiar face at both ends of the pitch at St Andrews on Saturday.
His Irish international team-mates Kenny Cunningham and Clinton Morrison are key men for Birmingham City.
Robbie will come face-to-face with defender Cunningham, now his Irish captain, while Morrison's pace will have to be watched at the other end.
"It will be nice to see Kenny and Clinton, good lads who I know well from Ireland," said Robbie.
"I know Kenny very well. It will be interesting to play against him and we'll have a laugh afterwards.
"He knows me but it's all on the day. Leeds knew me as well, but you just change a few things. Always expect the unexpected!
"Clinton's a good player, a good goalscorer who plays right up on the shoulder. We'll have to be wary of him."
Robbie knows exactly what to expect at St Andrews. "It will be a tough one," he said. "I've played there a few times when I was at Wolves and it's a hostile atmosphere.
"Hopefully last week's result against Leeds will give us the confidence to go there and win the three points.
"It would be a shame after last week's result having playing so well and getting the three points to then come away with nothing from Birmingham.
"It will be tough but there is a lot of confidence in the dressing room now."
