Southampton executive director Les Reed hopes Adam Lallana will commit to the club now Ronald Koeman has been confirmed as their new manager.
Koeman took over at St Mary's on Monday following Mauricio Pochettino's departure to Tottenham and the Dutchman is already aware several of his star players are seeking moves to bigger clubs.
Along with defender Dejan Lovren, Lallana has been subject to reported interest from Liverpool but Reed has urged the England international to stay at Southampton.
"Lallana's been here long enough, we've brought him to this level and we feel that perhaps he should give it a little bit longer," Reed told BBC South Today.
"Anybody seriously considering coming for our players are going to have to think very significantly about the size of the fee.
"If we do take money it will be because it's the right amount and it enables us to improve the team and move forward."
Koeman and brother Erwin, who was announced as his assistant, must work quickly to resolve the future of their key players and it is understood Ronald will take English lessons ahead of the club's pre-season campaign.
