Manchester United were dealt a blow in their hopes of reaching the Champions League next season after the Red Devils crashed out of the Europa League on Thursday night.
Philippe Coutinho’s brilliant goal cancelled out Anthony Martial’s opener as United drew 1-1 with Liverpool, which saw the Reds progress to the quarter-finals 3-1 on aggregate.
The Citizens, meanwhile, played out a disappointing goalless draw with Dynamo Kyiv mid-week just days after a 0-0 stalemate with Norwich City in their last Premier League outing.
City are four points ahead of sixth-placed United in the race for a top-four finish as both Manchester clubs limp towards the season’s conclusion.

“City started the season so well and looked like they would run away with it but they’ve totally imploded. I wouldn’t put a lot of money on one team or the other.”
City and United played out a goalless draw at Old Trafford in the Manchester derby earlier this season.
