Liverpool slipped out of the Champions League as their hopes of a comeback against Real Madrid faltered on Wednesday.

A much-improved performance from the first leg will at least give the Reds some encouragement after they were held to a goalless draw in their quarter-final return.

The result means Jurgen Klopp’s side must now concentrate on regaining their place in the competition next season over the closing weeks of the campaign.

But there was plenty that went unnoticed or under the radar during the 90 minutes at Anfield.

Zidane smirks

Anyone who has sat through a Zinedine Zidane press conference will know the Real Madrid boss doesn't like to give much away.

But the mask slipped momentarily during a major flashpoint in the first half when Casemiro went straight through James Milner on the touchline before shoving Andy Robertson.

While Jurgen Klopp and the Liverpool bench fumed, Zidane could be spotted in the background with a wicked grin on his face as the melee transpired.

Mind you, given how the Frenchman ended his playing career, we perhaps shouldn't be surprised.

The Casemiro miracle

That Casemiro was able to make such a challenge was borderline miraculous.

The Brazilian had only moments earlier seemingly been left with his career hanging in the balance after a tangle with Fabinho near the centre circle.

But after requiring lengthy, time-consuming treatment and then hobbling around for a few seconds, the Real Madrid swiftly regained full fitness to steam into Milner.

Casemiro? Just call him Lazarus.

Bjorn Red

Real Madrid didn't offer much going forward, particularly during a first half in which Liverpool dominated.

And when they did threaten before the break, they found themselves having to overcome a 12th man in the form of referee Bjorn Kuipers.

Well, at least that's how it appeared when the whistle-blower temporarily turned into Fabinho by accidentally getting in the way of potentially dangerous Real attack.

Perhaps the Dutchman was subconsciously atoning for the poor officiating from his colleague Felix Brych in last week's first leg.

Key Liverpool duo return

Virgil van Dijk and Jordan Henderson were back at Anfield on Wednesday night.

Unfortunately for Liverpool, though, it was merely as spectators.

The duo were among those sat behind the dugout in the Main Stand to help provide some extra backing with no fans present.

They will hope it isn't the last time they see Champions League football at the stadium for a while.
