You may be correct but from that angle I can't see much skin. I think the OP mentioned nipple but I couldn't say his shirt was up that far, but there was definitely an occasion when his shirt was pulled up quite high.
I also saw this but had completely forgotten it in the myriad of other var threads. What an accursed thing var is. It is pretty disgusting that west ham got away with that, so all those saying 'yeah but var will even out' well it didn't in that match at all and completely favoured w ham.
