He's been playing well lately, with the ball at his feet he will always struggle but in space he is fast and strong enough. The assist was great.
Also I love the mentality, defensively he's not easy to beat and offensively despite the critics and some of his teammates (mainly Barella) always telling him off, he's always making the runs, trying. He has the right energy for a wing back.
Theo wouldn't be able to make those runs against us because both Darmian and Dumfries would rather rugby tackle his ass to the floor than let him score that easily.
