And while Cornwell knows he is unlikely to ever be the Tigers' first choice No.10, the 28-year-old believes he still has plenty to offer his home town club - both on and off the field.
The former utility back's travels took him to Exeter Chiefs, Northampton Saints and Mogliano in Italy where he played full-time as a fly-half for the first time before returning to Leicester last summer.
"My last game at Welford Road was in the Premiership against Bath five seasons ago, so the win was special," said Cornwell.
"I had to leave the team but I always wanted to come back. I was in Italy last year basically on the advice of Jim Mallinder at Northampton.
"I went there for a year but only played once in the LV=Cup, and he said with the way the game was changing I should go and try and be a proper No.10. So I joined Mogliano and it was brilliant, I played every game and I loved being in control and being more involved.
"But I was always pestering Richard Cockerill when I saw Billy Twelvetrees and Jeremy Staunton were moving on and retiring, and he knew how my game had evolved as a player.
"I knew exactly what was expected of me and I was happy just to get back and give it my best shot. I do a job most weeks helping prepare the team and when I'm needed to play I step up and give it my all."
And Cornwell's experience could prove vital over the next few weeks as Leicester wave goodbye to a raft of first team regular for the duration of the RBS 6 Nations.
Despite playing a number of young tyros in the victory over Wasps, Leicester still romped home running in five tries along the way - something Cornwell thinks is vital if they are to progress further in the LV=Cup and maintain their recent momentum.
"We had a very good, very thorough week's preparation leading up to the Wasps game," revealed Cornwell, who helped Mogliano to their highest ever finishing position in the Super 10 last season. "We did our homework and kept playing, although there were a few little things to work on in training.
"But overall we are really happy - we were at home and we gave the 20,000 fans who were there what they came to see. Over the next few weeks we are going to have our international players away and it is up to the rest of the players to gel as quickly as possible.
"I've just turned 28 and I've played for four clubs and seen some different cultures and environments and been exposed to ten or 12 different coaches, and I suppose you pick up a little bit from everybody.
"I think I'm more mature as a player and more rounded and I suppose most players expect to play their best rugby in their late 20s. Leicester give everybody the opportunity to be the best they can be and when the whole squad have that mentality - which it looks like we have this year - the club can do well.
"We are on a nine-game winning streak which almost becomes more important in itself as those wins breed confidence. Leicester is my home club, it's where I was brought up and brought to watch rugby as a kid since I was five years old.
"My goal is just to be associated with Leicester for as long as possible in a playing capacity and when I get the chance give the coaches a selection headache."
