Rojo didn't look out of sorts at all in this match. His defending, whenever he was called upon to it, was very good and composed, and he looked settled in defence alongside Smalling. He was also very good at passing the ball around, and he played much better than he did at the beginning when he looked somewhat shaky.
He still has those one or two moments where he presses too hard and loses his man. A couple of times, Aluko went past Rojo too easily because Rojo pressed Aluko too hard. The yellow was also a result of that. van Gaal has done a great job controlling Rojo's aggression, and I give credit to Rojo for playing less instinctively. However, he still has those very few moments of over-aggression that I'm sure he can eradicate, especially under van Gaal.
