Eintracht Frankfurt coach Adi Hutter admits they could lose Sebastien Haller in the coming days.
The striker is the subject of major interest from West Ham, which have tabled a 40m offer, reports Kicker.
Hutter said, "From a sporting point of view, it would be a big loss for us.
"It is a decision of the player, if he says 'okay, I would like to leave the club', because the whole package is correct. Then..."
Hutter admits he would try to convince Haller to stay.
"Of course, I will try to make one or another proposals to the player."
