Wigan Athletic boss Roberto Martinez insists he is not worried about other clubs showing an interest in Lee Cattermole.
The midfielder only joined the Latics last summer for £3.5million from Middlesbrough and enjoyed an impressive debut campaign at the JJB Stadium.
He also caught the eye during England's run to the European Under-21 Championship final and has been linked with several Premier League sides.
Former Wigan manager Steve Bruce reportedly wants to take Cattermole to Sunderland, while Liverpool and Tottenham have also been mooted as admirers.
Latics chairman Dave Whelan has already stressed the 21-year-old is not for sale and Martinez is confident Cattermole can continue to progress at his current club.
"I am not worried about the situation with Lee, as he is still a young man and you want that interest," Martinez told the Wigan Evening Post.
"I want the top clubs in world football to be talking about our
players and about our football club.
"I prefer that to people not talking about our players. That is always a bad sign.
"It is down to us to keep progressing and making sure we are allowing these players to remain motivated and have the incentive to continue progressing. That should be part of our growth as a club and we need players like Lee around to do that.
"It is important that Lee has his targets and keeps developing as a player, and we hope he can fulfil his potential.
"We have all seen he is a leader and someone who can go to the very top in world football. To have a player like that at your club is very exciting."
