Got my shirt the other Sunday. Wore it once to play 5 a side and it's resulted in two small pulls right under the Etihad printing.
I've had last three seasons Umbro shirts and they've been worn twice a week for five a side, thus washed twice since they launched until the new one launched and they are all in top order. Not a single mark, pull, loose thread or tear on any of them.
I've also got a Spain away shirt which sometimes gets a run out, this is made by Adidas and it's the silky fabric but this too has never pulled.
I think the loose spun fabric design is at fault here, it's not great to be honest. And I feel a little aggrieved to say the least.
