Mourinho has not delivered the Premier League title in his second season in charge, and the failure to progress to the FA Cup final is likely to increase the negativity around the Portuguese's managerial position.
The hosts threw everything at West Brom in the closing stages, but were unable to find a breakthrough that would have delayed City's title confirmation until at least Wednesday when United take on Bournemouth. "We're going to Shrewsbury", they sang early in the game.

With that kind of ability, drive and precision, Jose Mourinho's team would be able to win the title next season.
United midfielder Nemanja Matic had headed a corner across his own goal area and Rodriguez reacted quickly to nod home the victor. He has a very good squad, but he needs to get more from it. Paul Pogba needs to significantly improve, as does Alexis Sanchez.
"It hurts [for Manchester City to win the title]". Anthony Martial and Marcus Rashford need to be more consistent. Caretaker manager Darren Moore was obviously pretty pleased with the win as his side put in an astute defensive display in the dying minutes of the game.
"We were masters in complication, everything was complicated", Mourinho said during his post-match interview. He was the reason why the Devils could not score from those few opportunities they managed to create and teams from the mid-table and lower end of the Premier League will be looking at Foster during the summer. I think with my experience you don't win titles with inconsistency. Everything was complicated.

"I believe in myself, but I don't play", said Mourinho.
"Everything was one more touch, one more flick, one more pass, one more touch", Mounrinho added. Yet, in order to do that, they would have to repeat performances like that one for the best part of the 38 matches.
