The Reds have been in the market for a right-back all summer to offer competition to Tendayi Darikwa.
Forest boss Aitor Karanka has been keen on adding Byram to his squad and confirmed his interest yesterday.
And a Hammers insider on Twitter has offered fans an update on one of the window’s drawn out transfers.
“Forest offered a loan, we want to sell! Last I heard we were trying to come to an agreement where by the loan fee is higher and the final purchase is therefore lower and I think talks are still on going,” posted @ExWHUemployee.
