Montpellier coach Michel der Zakarian admits they risk losing star striker Elyi Wahi this summer.
The youngster is being followed by Arsenal.
Wahi, 20, has impressed in Ligue 1 this season after scoring 12 goals in 24 appearances for Montpellier.
This form has already seen him linked with a move to the Premier League, with Arsenal among the potential suitors.
Bundesliga giants Borussia Dortmund are also reported to be keen on Wahi.
Der Zakarian said: "The kid, he's 20, and full of talent. That costs a lot. For me, minimum 25-30m.
"When you see the TV rights over there, England can buy him. It's easier for them."
He added: "Where he can improve? He needs to work on his volume, needs to run a lot more, always be moving and be in a position to repeat the efforts. If you don't have the fitness
"He's a sprinter, he goes really quickly, but sometimes he's knackered after 45 minutes.
"He needs to work a bit better, that's every day at training. If he wants to play in a big club and play with great players, he needs to work hard. He can go very far, at a very, very good level.
"Scoring goals like he does, you need to put them in the back of the net.
"What he does is good for his age, but I think he can do even better."
