Manchester have good players but what I saw in the game against Watford they didn't do well and didn't seem eager to play.
And if Manchester United's performance doesn't change and doesn't improve, I'm afraid the second leg match against Atletico in the UCL will lose because Atletico have a high aggressive game.
Manchester united has tried as much as possible to achieve full point, but watford disciplined and fairly solid game forced manchester to share 1 points, I think 1 point is a pretty good result for watford if you see their struggle for 90+4 minutes continue to withstand manchester attacks united, but the 1 point obtained by manchester of course adds to the difficulty for them to be able to secure the current top 4 position.
