Zola said in the Watford Observer: "There have been no bids as far as I know. I understand there will be speculation because he is a player who is doing well and there probably is interest in him.
"It is natural but I haven't heard any more than the rumours I have read in newspapers.
"As manager, I would of course like him to stay but should there be a bid, I'm sure there will be other things to consider. At the moment, it is difficult to comment.
"He is an important player in the team and I would like to keep him with us but we need to wait and see what happens."
