Eto'o has only a year remaining on his contract and if Barca do not cash in this summer or renew his contract they face the possibility of losing him for nothing next June.
Speculation is mounting that the treble-winners will use him as part of a cash plus player deal to snap up Inter Milan striker Zlatan Ibrahimovic, while the 28-year-old has also been linked with a move to Manchester City.
Laporta said: "Samuel has a contract and we're very happy with him.
"We want him to continue with us and for him to retire in the Barca shirt.
"But the market is very dynamic and there could be surprises. He's a wanted man and we know he'll receive offers.
"We want him to continue, he has a contract and let's hope he renews it."
