Hamburg chief Oliver Kreuzer cannot rule out selling young midfielder Hakan Calhanoglu next month.
Arsenal boss Arsene Wenger had scouts check on the attacker in action against FC Augsburg last week.
"We have no ambition to sell him. Also Hakan himself wants to prevail in the Bundesliga," argued Kreuzer.
"Of course there is for each player a pay threshold, but the issue of action lies with us."
