Arsenal chairman Peter Hill-Wood has admitted he fears losing Thierry Henry.
The Gunners' star striker is out of contract in 2007 and has been linked with a move to Barcelona.
The club are anxious to keep the 28-year-old but he has so far been unwilling to discuss a new deal and Hill-Wood concedes he could leave.
Hill-Wood told the Daily Star: 'At the back of my mind there is a fear he will decide to go.
'I have no evidence other than maybe I have been here too many times before with players and become cynical.
'I'm realistic enough to know that if he wanted to go he would and there is nothing we could do about it.
'It would be a shattering blow to lose him. We are as keen as mustard to keep him - he knows we are ready to talk about a new contract and will stretch every muscle to keep him.'
Henry, who joined Arsenal from Juventus in 1999, this season overtook Ian Wright as the club's record goalscorer.
