I watched the post match interviews and a few of the post match analyses and found a couple of things interesting.
Slott's Post Match Interview.
In this post match interview AS mentions 4 or 5 times that United played long balls and that is very difficult to play against. A few on here have taken offense at this comment saying it wasn't true. In Ian Wright's analysis he too mentions that 80% of the time, according to the post match stats, United went long with the ball.
I have been yelling for us to go long for weeks now, and stop this tappy tappy play out from the back, lose the ball, and concede a chance type of football. As Wrighty pointed out, the long ball gives you a 50-50 chance of winning possession and then you are already half the way up the pitch. If you don't when the 50-50 the your defensive line starts there and not 8 or 12 yards from your own goal when you have lost the ball with tappy tappy. There is nothing wrong with going long if you aren't great at playing out from the back. In fact it's the most sensible decision in that circumstance. However Slott was saying 'United just went long; and that is very hard to play against." as if it was somehow not gentlemanly conduct. Like playing tennis and hitting the ball too hard for your opponent to return. Isn't making it difficult for the opposition to play exactly what you should do ? It was a tactic and clearly by his complaining it worked. Well done Rubin.
Trent Alexander Arnold
The general opinion seems to be that Trent ( as the pundits like to call him) had a stinker. However Slott said that Trent's problem was that he had Dalot and Bruno running at him all afternoon. Wrighty's analysis showed that 53% of United's attacking play went down our left at Trent. Everyone knows that Trent is great at crossing the ball into the box, but not much cop at defending; so Rubin set us up to constantly run at him, with Dalot and Bruno double teaming him and making him look like a mug. Again a tactic that worked. Well done Rubin.
The idea that Rubin has just one way to play and won't change and won't be pragmatic was clearly shown to be false on Sunday. He totally out smarted Liverpool with his tactics even if Slott doesn't think that the long play is very fair and we should have played to our weaknesses.
He set us up to win and the players followed through by implementing the tactics and giving the requisite level of effort.
It was an all round great performance.
