West Ham are set to boost their transfer funds by selling Albian Ajeti to Celtic for £5million.
Scottish champions Celtic originally wanted to take Ajeti on loan with an option to make the move permanent next summer.
But West Ham manager David Moyes insisted on a permanent deal to increase his transfer kitty as he plots new signings to strengthen for next season.
Celtic then agreed to meet the £5m asking price for Ajeti, who is set to sign a four-year contract.
The 23-year-old Switzerland international joined the Hammers for £8m from Basel last summer but failed to score in 12 appearances last season.
Ajeti struggled for action under Manuel Pellegrini and then David Moyes and he did not manage a shot on target during a disappointing season at the London Stadium.
He is set to complete a switch to Celtic after being convinced to join the Scottish champions following talks with manager Neil Lennon.
