Valon Behrami's agent says the coveted West Ham star is staying put at Upton Park until next summer at least.
The Swiss international's performances for the Hammers since his £5million move from Lazio last year have alerted several clubs, with Arsenal, AC Milan, Juventus and Roma thought to among the sides keeping tabs on him.
But the 24-year-old's agent, Alessandro Beltrami, insists the versatile player wants to stay at Upton Park until next summer at least so as not to jeopardise his place in the Swiss squad for next summer's World Cup finals.
Beltrami said in the Daily Star: "It is possible for him to move after the World Cup next year but not before then.
"He doesn't want anything to affect his place in the Switzerland squad."
Meanwhile, Gianfranco Zola insists he is a warrior who can lift the Hammers out of their current predicament.
The Hammers currently sit second from bottom of the Premier League after only taking five points from their opening eight games.
But Zola believes he can turn it around, saying: "It's very difficult because I care about the players and the club. It hurts me.
"But I am a warrior - I don't look like it but I am one.
"I am someone who never gives up and my determination to succeed is stronger than anything.
"The job keeps me awake at night. You are always trying to find answers. But I want the players to look for solutions, rather than worry."
