Fulham manager Roy Hodgson has admitted he is concerned over Arsenal's interest in Brede Hangeland.
The Norway international defender has been linked with a move to Arsenal throughout the summer before Gunners boss Arsene Wenger officially confirmed his interest on Thursday.
Hodgson is desperate to keep hold of Hangeland, who has been key to the club's resurgence during his 18 months at the helm.
However, the Cottagers boss is worried by the interest shown in the 28-year-old central defender by the north London club.
"When a bigger club is interested or connected with one of your players, of course it is a source of worry because Brede is a very important person for us," he admitted.
"I sometimes have admitted to being interested or admiring certain players, but that doesn't necessarily mean you are always going to go and sign them.
"Because to sign the player would first require the club taking contact with us and then making certain everyone was happy with any deal that could be struck.
"I think we have got a long way to go before that happen."
