Mark Warburton has warned Wigan boss Uwe Rosler that Brentford’s prize assets won’t come cheap if he comes calling in January.

The 54-year-old took over the reins in TW8 on Tuesday after Rosler was appointed as Owen Coyle’s successor at the DW Stadium.

Warburton, who left his role as sporting director after being asked to fill the breach by owner Matthew Benham, confirmed there is no agreement in place to stop Rosler raiding his old club for their stars.

But the NextGen founder says none of Brentford’s players will be sold unless their valuations are met.

He said: “There’s no agreement in place to stop Uwe coming in for our players.

“I’m not worried because we’ve tied them into long-term contracts. The owner’s been sensible to look after the players.

“But everyone has a price. The fact Uwe has gone is on our terms as Wigan came in and met the compensation agreed in his contract.

“Likewise, if any players go they will do so with our best wishes because it would also be on our terms.

"If we lose a Harlee Dean, Adam Forshaw, Jake Bidwell or whoever they would go for our price.

“However, we want to keep them here. You wouldn’t offer them a three-year contract unless you think they add value to what you’ve got.

“No one is leaving here unless the owner is happy with the terms.”
