Throughout his career it has always been his attitude that has been questioned though. Even when he was in his pomp and had great pace and technical ability there were always huge question marks over both his temperament and desire.
I think its a symptom of his approach to the game plays with a focused look on his face, just look at the experts popping up every time Salah isn't grinning from ear to ear, all of a sudden he's unhappy, there's an issue and he definitely wants out.
Sturridge is one of those who seems to be fun and games at the right times but saves his serious focused times for match day, watch any behind the scenes video from the club and he's definitely one of the club jokers, the hip hop quiz and carpool videos being prime examples but watch him on the bench or warming up and its a completely different person. The guy has never had any sort of attitude problem from what i've seen, the main times its been levelled at him as a criticism that i remember
Left City in search of game time - Can anyone really blame him? All those years ago and yet you look at City today and young lads are still leaving there to actually get to play
Stated he feels his best position is through the centre when being played wide often for chelsea - Again, can he be blamed? Ask any player who isn't playing in their most effective position and you'll likely either get 'i'm just happy to help the team' or 'i feel i play best in this certain position but am happy to play in others'.
Serious look on his face on our bench - Again, he does it every single game, its not an attitude thing, he's not moody he didn't start, he does it when he's on the pitch as well, even when he was one of the first names on the teamsheet he still played with the intense focused facial expression.
