Andy Goode insists Juan Martin Hernandez will face a fight for the Tigers fly-half jersey if the Argentina World Cup star does complete his desired move to Welford Road.
Hernandez, who helped the Pumas to an historic third place last October, stated this week he wants to swap Stade Francais for a "new challenge".
Goode has been linked with a summer move in the opposite direction, with Brive one of the Top 14 clubs supposedly interested.
But after his virtuoso performance in Leicester's 34-24 EDF Energy Cup semi-final victory over Wasps, Goode vowed to remain at the east midlands club next season whatever competition there is for his jersey.
Goode said: "If he (Hernandez) turns up, he will have a battle on his hands.
"I have a year left on my contract at Leicester, I love the place and I have no intention of going anywhere."
