Bit of a coincidence that as soon as the club decide to print T-shirts of them for sale that their form drops or they get injured. Stop it now. Nobody's going to buy them anyway are they?
lol if you think that a t-shirt affects a players performance / somehow makes a player more susceptible to injury then you need to go back to whatever fairy land you are living in mate!
I got one as a present and thought it was hilarious!
