I've only seen the highlights but from the little I saw I would say they are not good enough for the Premier league.
It's a very high standard teams must aspire to for them to reach the top in English football, and the rags do not currently have that.
From what I watched of him Maguire -once again- proved that he is just not good enough at this level. The rags tried to play a high line yesterday, all well and good if you CAN do that, but whenever Brighton counter-attacked Maguire did not have the speed to get back quick enough, leaving them badly exposed. But even if he was the fastest man alive it would make little difference because he simply does not have the nouse to read a game and see what is happening. For a professional footballer the man is a disaster. He appears to only be in the side in order to justify the astonishing amount that joke of a club paid for him. They want their money's worth, even if it means having a liability like him playing.
