Brentford manager Marinus Dijkhuizen has admitted that defender Moses Odubajo is likely to leave the club this summer.
The 22-year-old has been linked with a move to Championship rivals Hull City in recent weeks.
Odubajo has two years remaining on his current deal with the Bees.
"I think Moses will not be in the squad any more so that's a big loss for us," Dijkjuizen told BBC Sport. "Hull bid for him last week and he decided for himself that he didn't want to play in [Saturday's friendly against Norwich City].
"He wants to leave. He said it's a big opportunity for him. I expect a Premier League club to bid because he's a very good player and there aren't a lot of good right-backs around."
Odubajo joined Brentford from Leyton Orient last summer for £1m.
