After just one win in the opening six rounds of Aviva Premiership competition, Tigers have enjoyed a run of good form and moved into the top four following the New Year’s Day win over Sale Sharks in front of a 23,000 crowd at Welford Road.
Tigers return to home ground this Saturday for the visit of London Wasps (5pm kick-off) and Cockerill says there will be no change in the attitude of the players.
“It’s very competitive in this league,” said Cockerill. “A couple of results you do not expect and you can go from fifth to 11th in the table.
“Wasps started the season really well and they were optimistic, but they’ve had a lot of injuries and they’ve had a bit of a tough time.
“But we know how just quickly that can change. You can enjoy your wins but you can’t be complacent after a win because games come too quickly for that.
“We know we have to keep picking up points and keep moving up the table because every game is a tough one.”
Cockerill confirmed Tigers will be without the injured Manu Tuilagi and Louis Deacon after both picked up hamstring injuries in the Round 11 win over Worcester Warriors at Christmas.
Tickets for Saturday's game are available now from the Tigers ticket office.
