Overall, I must say, this was quite a decent performance. We're certainly heading in the right direction, and finally, we start with a formation that provides us some proper width.
van Gaal's methods are starting to sink into the team, which is great to see. We're passing the ball around quicker, and we're creating more spaces in the middle than before. Thankfully, this is down to the width that Young and di Maria/Januzaj provided. In the end, van Gaal always gets back to the 4-3-3/4-2-3-1/4-4-1-1, and I hope he sticks with this from here on in.
One problem that I noticed is that we badly miss that creative #10 that is a huge component of any of van Gaal's teams. Rooney is not creative enough behind the striker as he's more of a goalscorer than a creator, and this requires us to have a creative player from central midfield trying to take risks, which conflicts with what van Gaal wants from his central midfielders. For the whole match, our main creative outlets were from the wide areas whilst we had barely any from the middle. This match was perfect for Mata as he's a very creative #10 whilst still being a good goalscorer (van Gaal's ideal #10, in a way). No wonder our players looked more ponderous in the final third through the middle.
However, I do understand why he put Falcao up front. With his wide players also being creative outlets, we need a presence in the box to get on the end of crosses. Playing Rooney up front with Mata will make it easier for Sunderland to defend crosses into the box, and we'll be forced to try to create chances through the middle, the same area Sunderland would have congested. Instead, with Falcao being great in the air (even if he is off form; just look at how many of his goals are headers), we have the wide as well as the middle areas to create chances from. Sadly, di Maria wasn't at his best, whilst Falcao was poor on the ball along with not getting much service. The second half was much better in this regard even if we were down to 10 men.
One huge, huge problem that I notice is that we are still very poor at pressing the opposition. How is it that we always give the opposition player an option when we're pressing them? How are we so poor at pressing the opposition and quickly closing down their options with players like Herrera, di Maria, Blind, and Valencia, all of whom are very good at pressing the opposition and closing down their options? Herrera, Blind, and di Maria all played under coaches who are very good at implementing the pressing game (Bielsa, Jorge Jesus, Mourinho, de Boer, and van Gaal himself), yet, even with these players, we are still poor at closing down the opposition! I feel like I've said this too often, but we really need to sort out our pressing game; otherwise, we'll be conceding chances far too often.
