Chief executive Simon Cohen says the fact Matt Cornwell understands the Leicester Tigers culture played a big part in the decision to re-sign him.
The 27-year-old centre/fly-half spent four years at Welford Road from 2004, before joining Exeter and Northampton.
He will return to Tigers after a spell with Italian Super 10 side Mogliano.
Cohen told BBC Radio Leicester: "Matt will train really hard and work really hard and do a great job for the environment and the culture."
The Tigers chief executive added: "Richard Cockerill [director of rugby] is very careful and protective about the Leicester culture.
"He thinks it is really important and Matt understands that culture.
"Matt has developed as a player in the time he has been away and will do a job on the park as well."
