Four Things We Learned From Man Utd's Disappointing 0-0 Draw With Valencia in the Champions League

Manchester United's disappointing season continued as they were held to a 0-0 draw against Valencia in the Champions League on Tuesday evening.

Once again, United were far below par and their performance warranted no more than a point. Jose Mourinho's men had a few chances to snatch a win late on, but were ultimately found wanting in front of goal.

Here are four things we learned from Tuesday's clash.

4. Marcus Rashford Deserves to be Given a Chance Up Top

There were barely any decent performers on show for Manchester United, but Marcus Rashford at least seemed to be trying to make things happen out wide.

However, he has always tended to be more effective when operating centrally and he should be given the chance to flourish there after Romelu Lukaku's abhorrent showing. 

The Belgian striker was clumsy on the ball and was far too static when he should have been looking to get in behind the Valencia defence.

Whether or not Mourinho will trust Rashford to lead the line is an entirely different question in itself, but the youngster deserves to at least be given the opportunity to prove himself - even if its only for one game.

3. Maurone Fellaini and Nemanja Matic Should Not Play Alongside One Another

If you're looking for a midfield partnership that will provide dynamic transitions from defence to attack, then Nemanja Matic and Marouane Fellaini aren't the answer.

The duo are sluggish enough as it is, but they ended up being sloppy on the ball and gave it away needlessly on far too many occasions.

Having a two-man anchor behind Paul Pogba could certainly work, but one of Fellaini or Matic needs to be dropped in favour of the more athletic Fred, who can carry the ball at his feet with a lot more purpose.

2. The Idea of Playing a Back Five Needs to be Quashed

For all of United's many faults, they at least kept a clean sheet which is a far cry from their torrid defensive performance against West Ham on the weekend.

The experiment of using a back five went horribly wrong in that one, and despite keeping Valencia at bay, it needs to be kicked into the long grass for good.

This doesn't mean all of their defensive issues will be solved, but it would be suicidal for them to even consider switching up the back line again. Rotating his defence seems to be at the forefront of Mourinho's plans, so anything could end up happening against Newcastle on Saturday.

1. Mourinho's Expiration Date Just Got Shorter

At this point, it is safe to say that everybody at Manchester United believes that Jose Mourinho isn't going to last until the end of the season.

In fact, at the rate he's going he isn't going to make it until Christmas, and his side's performance against Valencia probably decreased his shelf life even further.

None of his players look as though they are playing for him, he doesn't seem to have any sort of fight left in him during his post-match press conferences and the Red Devils look as though they are as far away from competing with Europe's elite sides as they have ever been.

Once again, Mourinho's third season curse looks like it's coming true.
