Brentford have accepted a bid in the region of £40m for Ivan Toney from Saudi Pro League club Al-Ahli.
Sources close to the England forward say they believe the deal will go through, and Toney will complete the transfer.
Toney, 28, has not played for Brentford so far this season and manager Thomas Frank has already ruled him out of Saturday's game against Southampton.
Napoli striker Victor Osimhen has also been linked with a big money move to Al-Ahli.
The Saudi transfer window does not close until 2 September, so Toney's transfer does not have to be completed by the Premier League deadline of 23:00 BST on Friday.
Toney was part of Gareth Southgate's England squad at Euro 2024, although his three appearances - including in the defeat by Spain in the final - were all as a late substitute when England were chasing the game.

He was left out of interim England manager Lee Carsley's squad for September's Nations League games on Thursday.
Toney scored 20 goals in the 2022-23 Premier League season and netted four times in his first five matches last season after returning from an eight-month suspension for breaching FA betting rules.
