Celtic manager Neil Lennon wants his side to exact revenge in the Scottish Communities League Cup this week.
The Bhoys were beaten 2-0 by the Saints in the Scottish Premier League last month and Lennon is intent on getting one back in the league cup quarter-finals tonight.
"There will be a bit of revenge in the air," said Lennon whose side also lost to Kilmarnock on the weekend. "I'm sure the players will be very motivated. I'm looking for a really good reaction and I'm sure I'll get that.
"I'm not going to give my team away but it's fair to say it will be a pretty strong team.
"It's a quarter-final, off the back of a disappointing performance and result, and it's important we bounce back in the right way.
"They know how important the shirt is, they know how important it is to play for the club. They didn't do themselves justice on Saturday and it's not often I can cast that aspersion on the players. That's gone and we move on."
