Except an above average ability to cover ground due to the combination of good engine and long strides, I have yet to see anything that stands out. And he's over 23 already.
Not a tackler like Palhinha, not much of a dribbler unless there is wide open space in front of him, and certainly not a playmaker. He has the odd good game, like the one against City early in the season, where he shines as a disruptor that regularly breaks up play; but is that enough? Not for me.
But he's not our biggest issue! is becoming a huge cop-out when it comes to these average players by the way; have too many of them in the same squad, and they suddenly are a significant issue. The same line was used for someone like Johnson as well, yet selling him was the correct move. Sarr is also heading in that direction.
