Watched him last night, and wondered who we have that could have done a better job if fit.He gave so much, he won balls in the air, good tackling, good distribution, genuine pace and I have rarely seen anyone break from the centre of defence so quickly and confidently to assist Tierney in setting up the second goal. I think he just stunned Sunderland with that run.I am a big fan of Whitbread, and to a lesser extent Ward. De Laet has made a few to many mistakes but still looks class.But I genuinely don''t believe any of those players could provide a more convincing all round performance than Martin last night - surely he would have to make some big mistakes to be dropped even when the other centre backs are fit!
