Werder Bremen general manager Klaus Allofs is not attempting to sell players, but would listen to offers amid ongoing reports of Arsenal interest in Per Mertesacker.
The Germany international has been linked with a move to Emirates Stadium for several years and the rumour-mill has increased this summer.
Following the sale of Cesc Fabregas to Barcelona and the impending transfer of Samir Nasri to Manchester City, Arsenal boss Arsene Wenger has money to spend.
Giant centre-back Mertesacker is considered to be a player who would improve the Gunners, and Werder have previously said a possible sale would be a decision of boss Thomas Schaaf.
Allofs is not actively looking to offload players, who could also include Marko Arnautovic and Marko Marin, but he would consider official approaches.
He told Kreiszeitung Syke: "I am ready for everything, but I can insist we have not been offering any player of this club to another club.
"Should there be concrete offers, we will consider them then. This has not been the case thus far.
"My experience tells me that there are some experts on the scene that will only start to do action in the final days of the transfer window. Should this be the case, we would also be around."
Earlier in the week, Germany Under 21 international Kevin Schindler left Werder to join last season's rock-bottom Bundesliga club, St Pauli, on a one-year contract.
But Arnautovic does not want to follow Schindler out of Bremen, who host Freiburg this weekend, despite claiming to be the subject of approaches from other clubs.
"There are enquiries, that is a fact," he told BILD. "I am unaware of how concrete those enquiries are.
"I have not spoken to anyone and I also plan not to speak to anyone. I am just focused on Werder Bremen. I want to play for this club. This is my future."
