Russell Martin is preparing to welcome Djeidi Gassama as his seventh summer signing. The transfer is experiencing last-minute hitches due to Sheffield Wednesday's financial difficulties. The club's owner, Dejphon Chansiri, is stalling on the £2.5 million sale to potentially attract rival bidders. Despite this, Martin expects Gassama to complete his switch to Rangers and sign a four-year deal, as the move is considered beneficial for the player's career. Transfermarkt currently estimates his market worth at 2.00 million euros.
