The last time Liverpool faced Atletico Madrid, Jurgen Klopp was furious people were attempting to shake his hand.

In the Spanish capital on Tuesday, though, he was left wearing a wry smile after being snubbed in such a manner.

At the end of a ridiculous rollercoaster of a Champions League night, Klopp sought out counterpart Diego Simeone for the traditional post-match handshake only to find the angry Atletico boss had long since bolted down the tunnel.

"I wanted to shake his hand - we are both emotional," said Klopp. "He was angry with the game - nothing else. When we see each other again we will 100% shake hands."

It was a memorable encounter that had just about everything. Well, almost everything.

Goals. Penalties awarded and not awarded. VAR interventions. Yellow cards. A red card. Not to mention a whole host of other stories within stories as Liverpool ultimately put one foot firmly in the knockout stages by recording a third Group B win in three to extend their unbeaten run in all competitions to 21 games.

When the teams met pre-pandemic at Anfield in March 2020, Klopp wasn't impressed, either with fans who sought his embrace as coronavirus restrictions kicked in, or the negative style of play that ultimately earned Atletico a 3-2 triumph and eliminated the Reds.

If the scoreline was reversed at the Wanda Metropolitano, the roles remained largely the same - Liverpool on the front foot, Atletico wanting to scrap, spoil and niggle their way through the 90 minutes.

But Simeone's side are Spanish champions for a reason. And their undoubted quality - along with some pretty shoddy Reds defending - meant Atletico had recovered from conceding two early goals from Mohamed Salah and Naby Keita to level the score and take the ascendancy by half-time.

The game changed when Antonie Griezmann, who had scored twice, was red-carded for a high boot into the face of Roberto Firmino seven minutes into the second half.

Even then, Liverpool - far, far from being at their best - needed the gift of a penalty tucked away by Salah when Mario Hermoso stupidly fouled Diogo Jota, along with referee Daniel Siebert then changing his mind after initially penalising Jota in his own box moments later.

With each passing moment, Simeone became more and more agitated on the touchline, his fume increasing to the point he dropped to his knees when substitute Angel Correa struck Atletico's last chance of the match well over the crossbar during a volatile injury-time period.

While Klopp sought to smooth relations with Simeone earlier this week with respectful praise, the Atletico boss simply shrugged his shoulders when pressed on his previous criticism.

He probably won't be quite as indifferent before the teams meet again at Anfield in a fortnight.

Same drama again? We will all shake hands on that.
