Manchester United fans have everything crossed ahead of their clash with Leicester City.

The Red Devils could have sewn up Champions League qualification ahead of the final weekend, but draws against Southampton and West Ham have put the situation on a knife edge.

Sure, it's still within United's hands to qualify for Europe and they're sitting pretty in third place, but their trip to the King Power Stadium won't half feel like a cup final.

Race for the Champions League

And if the scoreline isn't going their way against Brendan Rodgers' men, then they'll have to keep a close eye on what Chelsea are able to achieve against Wolverhampton Wanderers.

However, what we do know for certain is that more teams will be going away from the final day happy than sad because two out of three teams will qualify for the Champions League.

Or will they? Well, a bizarre rule could actually mean that Manchester United, for example, could finish fourth in the table and still find themselves absent from Europe's premier competition.

Potential plot twist for Man Utd

We explained a few weeks ago that a bizarre rule means that if English teams absent from the top four win the Europa League and Champions League then fourth place no longer qualifies.

And per the Express, that's still a tangible possibility going into the final day of the season and they've worked out the three stages that would happen if United are to suffer heartbreak.

So, buckle in United fans, here are three things you need to be avoiding over the next few months:

Step one: Man Utd finish fourth, Chelsea finish fifth

First and foremost, United need to wind up in fourth place, below Leicester City and Chelsea would need to finish outside of the Champions League spots. So, how could that transpire?

A Chelsea defeat would see them stay below United on goal difference who, if they lost at the King Power Stadium, would be usurped by the Foxes and remain in fourth by the skin of their teeth.

In layman's terms, both United and Chelsea would need to lose later this afternoon.

Step two: Wolves win the Europa League

Part of this weird scenario working hinged on the fact Wolves did not finish in the top four which, in fairness, was on the cards at one point, but it's mathematically impossible going into the final day.

So, they now need to casually win the Europa League... what can possibly go wrong?

It's not completely out of the realms of possibility - this is a sport where Greece won Euro 2004 and Leicester won the Premier League, after all - but they'll face tough opposition from European giants.

Step three: Chelsea win the Champions League

By far and away the most unlikely part of this scenario is Chelsea overcoming a 3-0 first-leg aggregate defeat against Bayern Munich to win their second European Cup.

Nevertheless, miracles can and do happen so a massive turnaround at the Allianz Arena could inspire Chelsea to get revenge on United for booting them out of the top four.

If they do indeed get their hands on 'Big Ears' it would mean that they would quality for next season's Champions League despite finishing lower in the table.

Nearly impossible... but not quite

Each step gets less and less feasible, doesn't it?

But if Leicester are able to win against United and Chelsea come unstuck against Wolves, then United fans will face the real possibility of having to watch August's European action very carefully.

It would require a Chelsea miracle, don't get us wrong, but United pipping them to the post would be the perfect motivation and it's not as though they haven't won the Champions League against the odds before...
