I think that pretty much everyone agrees it was a dreadful performance. Unfortunately, Mourinho's style makes his teams extremely painful to watch when there's no pay-off (a win) at the end of the game.
What puzzles me is why he felt it necessary to introduce Sissoko at half-time. They had the best chance of the first half but despite our complete lack of creativity, we still managed to test Pickford on a couple of occasions. What was Sissoko supposed to add to the team? He's powerful (sort of) but they weren't really bullying us. He's not strong enough defensively to neutralise someone like Rodriguez. He's a bit of an all-rounder, a guy you might find useful when a more important player is missing for a game or two, but I really never saw him as a guy you could bring in a half-time in a tight match to make a difference.
Guess I was right, judging by today's 'performance'...
