Manchester United were subjected to humiliation when they missed out on a Champions League spot to rivals Manchester City in May.
For a second time in three years, the Red Devils faced the prospect of playing in the Europe League whilst watching their title rivals compete for domestic football's biggest prize.
And no one has let them forget about that fact - not even UEFA apparently.

In late July, United - and Zlatan Ibrahimovic - were inadvertently trolled by the Europa League's Twitter account, who tweeted a picture of the striker alongside the caption "Coming soon to the #UEL".
Well, the Champions League's account has now rubbed salt into the wounds by posting an innocuous yet hilarious picture of Old Trafford with the captain "It's back next week #UCL" (see below).
UEFA TROLL MAN UTD
In case you don't understand the significance of UEFA's tweet, they've essentially used United's stadium to promote a competition that they won't be competing in this season.
Twitter certainly saw the funny side of it anyway. Here's the best reaction.
While Jose Mourinho has previously admitted he rues the fact United aren't in the Champions League, he recently explained how it's also UEFA's loss that his side won't be competing.
He told BT Sport last month, per the Daily Mail: "Manchester United has to be in the Champions League.
"I think that the Champions League is empty when Man United is not there. Imagine the Champions League without Man United, Real Madrid, Barcelona.
"There are a certain number of clubs that make it not a Champions League without these clubs. That’s Manchester United and their natural habitat."
