3) He Possesses A lot Of Talent But There Are Question Marks About His Mentality
Vieira’s attitude wasn’t only questioned when he was a youngster. Two years ago, Porto boss Sergio Conceicao delivered a public rebuke of the player’s mental toughness and lack of commitment to fulfilling his tactical role.
That may raise some alarm bells considering Arteta’s lack of tolerance for players who don’t toe the party line (such as Matteo Guendouzi, Pierre-Emerick Aubameyang and others). It does seem like Vieira has taken the criticism on board, though, when we look at his performances last campaign.
