United look very confident in counter attacking situations and executed very well. That aside, I don't think they looked very good bar their new CB pairing. Chelsea's poor control of the ball and lethargic pressing handed easy possession to United which it made it a very comfortable afternoon for the boys in red. Would have been interesting to see how United reacted if Abraham had actually taken that early chance.
Overall, not worried about this United team over the course of a season. They have a Europa League campaign to manage as well and while more capable defensively, doubt its enough to challenge for a top 4 place. Also, Pogba is even more important for them now and a serious bid from one of the continental giants could easily unsettle him.
Chelsea will get better. Were very naïve and fitness and discipline can only get better after that showing. Again not overly worried. Think they are a more likely outfit to challenge for top 4 than United, but feel we definitely have the edge. Having Auba and Laca makes a big difference.
