Hull City have reportedly made a £9m bid for Brentford pair Moses Odubajo and Andre Gray.
Bees manager Marinus Dijkhuizen recently admitted that he expects defender Odubajo to leave the club this summer.
The 22-year-old has also been linked with a move to Everton.
Gray, who scored 18 goals last season, is another Brentford player who is understood to be on the verge of departing the club before the end of the transfer window.
Hull have now made an opening offer to their Championship rivals for the duo, according to Sky Sports News.
Steve Bruce's side start the new season at home to Huddersfield Town on Saturday, while Brentford host Ipswich Town.
