Klaas-Jan Huntelaar, Paul Pogba and Patrice Evra show how to celebrate during Champions League drama

Who says you shouldn't celebrate against your former club?

It's been a week of high drama in the Uefa Champions League with emotions running high - not least at the Bernabeu where Ajax dumped holders Real Madrid out of the competition.

Then it was the turn of Manchester United to send their fans wild as they clinched a last minute victory over Paris-Saint Germain on Wednesday evening.

Amid all of the jubilation and despair - on and off the pitch, there have been a few stand-out incidents, not least the actions of Ajax's Klaas-Jan Huntelaar.

What did Huntelaar do?

The former Real Madrid striker was an unused substitute but he certainly burnt off some energy after the final whistle...

Now, respect is a key aspect of football and sport in general, but all too often we have seen players in recent times refusing to celebrate after scoring against their former clubs - or even not celebrating against any other team (step forward Mo Salah and Romelu Lukaku).

So, it's refreshing to see Huntelaar getting caught up in the moment and having some fun with the thousands of Ajax fans who had travelled to Spain.

One extra thing to point out - that appears to be Real Madrid shirt he is throwing around like a rag. Erm, respect?

Pogba and Evra cheer on United: 'I love this game'

Meanwhile, it was pandemonium in Paris as Marcus Rashford scored from the penalty spot to book Manchester United's place in the quarter-final.

In the crowd were Paul Pogba, suspended after his red card in the first leg, and fellow Frenchman Patrice Evra, who spent nine seasons at United.

That they were in the posh seats doesn't hold them back from celebrating, as shown by Pogba's Instagram video...

Evra can be heard towards the end of the video shouting "I love this game!" as he makes no attempt to hide his emotions.

There was also a touching image of manager Ole Gunnar Solskjaer alongside legendary former United manager Alex Ferguson and Eric Cantona, who remains popular among United fans after his spell at the club in the 1990s.
