Saud when they signed him they weren't buying what they thought they were. He had one good season at Stuttgart, where he wasn't even their best player, where he played a completely different role to what the mags wanted. Hes not a #9, he's not quick, he's not powerful in the air despite his size. He's a false 9 or a 10. He's not a bad dribbler, can pick passes/lay balls off, holds the ball ok and provides an outlet for other players to find space.
But I think the pace of the game here at the moment is too fast fir him, maybe too physical and Beheaddie hasn't a clue how, or the inclination, to play to his strengths. £70m for a player who Stuttgart got for free, who was playing in Bundesaliga 3 just a few years ago, is ridiculous.
