and again he is talking gibberish. He didn't choose Vidal or Arthur but chose Coutinho over them.
I don't want to spoil the party but Arthur is not adding dynamism.
He is as slow as Busi and Raki.
Plus he is the most sterile midfielder in terms of any happening in the opponent's half.
If you want possession and press resistance, Arthur is the man.
But fast, risky, direct, attacking, dynamism.
Those words have nothing to do with Arthur.
Except if dynamism is a slow, useless passing left and right in the middle of the pitch while the opponent is sitting in their half.
Frenkie, Roberto, Alena, Puig and Vidal are dynamic.
Cou and Rafinha somewhat.
Raki, Busi and Arthur aren't.
