Lote Tuqiri is determined to rectify the "embarrassment" of last week's defeat to Northampton and leave Leicester on a high with victory over London Irish.
The former Australia winger returns home to Sydney after tomorrow's clash with the Exiles to take up a contract with rugby league side Wests Tigers.
During his short stint at Welford Road, Tuqiri has helped Leicester to the top of the Guinness Premiership, with the victories over Wasps and world champions South Africa his most prized memories.
But Leicester were beaten 19-3 at Northampton last week and, with London Irish anxious to cement their place in the top four, Tuqiri insists his work at Welford Road is not yet done.
"It is going to be massive tomorrow," he said.
"I had a look at the draw before I came and saw London Irish there and they have got a lot of really good players and they are in the top four now.
"We got a bit embarrassed last week and this is the place to rectify some of those wrongs that we may have done down at Northampton.
"It has been a very enjoyable stay at Leicester, a totally positive experience that you remember for the rest of your life.
"The game against South Africa was awesome - I have got my DVD from the club as a souvenir - and to get two tries against Wasps on the back of a dominant forward pack was special.
"Hopefully I have got one more good memory in me and I can leave the club in a good way."
London Irish travel to Leicester on the rise having returned to the top four last week with a 29-14 victory over local rivals Harlequins, who face relegation threatened Worcester tomorrow.
The Warriors are just one point above Leeds and Sale Sharks at the foot of the table and are in desperate need of a victory to build on their 13-0 win against Newcastle last weekend.
The relegation battle continues on Sunday with Leeds at home to Saracens, whose early-season form has stuttered, while Sale host Northampton.
