No.
1) Far too expensive, all the indications of a panic signing which make us pay through the roof for a defender that likely won't have that good of an output
2) Very error prone and wanders way too much, not to mention recklessness and obsession with being an attacking player. He's best as a DM, the Confeds cup proves nothing in his case as Brazil was heavily protected by having Silva and a double pivot.
He has potential and is a fan-favorite type player, but efficiency is what we need in a defender and that's not his forte. I don't care if he can pull off the spectacular every now and then, he'll still most likely be a liability from what he's shown in the past.
