Posture, cut of the GK top, breeze direction... no doubt he looks heavier now than then but as an athlete ages that is acceptable. If he is over weight and that is affecting his performance in training and on the pitch then I would expect the club to act. I follow our keepers closely, have done for years, was a GK myself & coached by no less than Monty in the 80s at a centre of excellence for a 1st Div Club (so what I know), the errors at Leeds & on Sat were very similar, he needs help and support, half a stone (maybe) makes no odds in comparison to mentality.
