Leicester Tigers director of rugby Richard Cockerill says his side must not sulk following their exit from the Heineken Cup at Leinster last weekend.
Cockerill told BBC Radio Leicester: "We can't let our heads drop and start to sulk. I think the measure is how you react when things don't go your way.
"We've got lots to play for. We've got Gloucester this weekend and still an opportunity to win the Premiership."
Tigers currently have 66 points from 19 Premiership game this season, three ahead of second-placed Saracens.
Cockerill's side host third-placed Gloucester at Welford Road on Saturday (1500 BST).
"We discuss how we want to improve and we get out on the training field and do it," Cockerill added.
"That's the key - players just want to play and get the bad memories out of the system and look forward to winning.
"We are at home in front of hopefully pretty much a sell-out crowd and it's a huge game this weekend."
