I guess the question I would ask is on what basis you think this?
He didnít shine in a balanced Barcelona midfield and he didnít particularly shine at Valencia either, what gives you this faith in him?
Firstly, it can take players from abroad a season to settle in the premiership. A manager will consider that. Roberto Firmino was considered a flop in his first season, 2015. I could name countless others and so could you.
He his not at the level needed to play at Barcelona, the best side in world football arguably, otherwise he wouldnít be here. They also require a particular style of La Masia player that is a rare quality to find. Arthur Melo seems to have it.
Did you watch him at Valencia? He was outstanding. Thatís why Barcelona signed him in the first place. Also, when he signed here, he was the best player for us until after the Derby. He was the best player on the pitch in the Derby and demonstrated qualities we just donít have in the middle of the park. Keep hold of the ball, skill, can play box to box, strength, can pass the ball forward.
He looked knackered around Christmas at a time he is not used to playing (also hardly used at Barce) and has been part of what looks like an unbalanced side.
He also has good work rate. Take a look at some of those performances for Valencia and re visit the Derby at Anfield.
