KENNY Jackett believes Millwall would be taking a backwards step if they were to sell star midfielder Liam Trotter.
Trotter is reported to be a January transfer target for Southampton and Fulham but Jackett says cashing in on the 24-year-old would hamper the Lions' progress.
Watford boss Gianfranco Zola, speaking after the goalless draw between the two sides in midweek, admitted he was not surprised to see the former Ipswich Town trainee linked with a move to the Premier League.
But Jackett said: "We want to build and, if we can, move up this division on a consistent basis. We won't do that by selling our players.
"We haven't had any inquiries or bids for Liam. Those rumours rumble around from time to time. But to some degree that's good, because it means you're doing something right.
"If your players are being linked with other clubs higher up, it usually means they're playing well. It's not something that we necessarily invite.
"He's played every minute of every game so far this season. He has half a dozen goals from midfield this season which is a very good total."
