They conceded 48 goals in 46 games and they played him in midfield some of the time, he got in the team of the year and was their runner-up player of the season. He's never going to be the best centre-half ever but he won't look out of place for West Ham in this league.
Tomkins was one of the most solid CBs in the champ last year, are you seriously going to judge him on a pre season match? So Green must be awful then???
