Racing magnate Dr Marwan Koukash will get his first sight of Salford City Reds tomorrow as he seeks to complete a takeover of the cash-strapped Super League club.
The 56-year-old Kuwait-born businessman and racehorse owner is still in negotiations with Salford City Stadium owners Peel Holdings and Salford Council to buy both the club and the ground.
It is thought a deal for the Reds is close to completion.
