Iker Casillas’ tweet hints he was unhappy with ref’s decisions in Liverpool 2-0 Porto

Liverpool beat Porto 2-0 in their Champions League quarter-final first leg on Tuesday night.

The Reds got off to the perfect start when Naby Keita’s deflected effort after six minute found the net.

Roberto Firmino scored 20 minutes later to double Liverpool’s advantage.

There were no further goals on the night, meaning Liverpool will head to the second leg next week as the overwhelming favourites to progress to the last four.

The result could have been very different, though.

There were a few controversial decisions on the night than didn’t work in Porto’s favour.

With half-an-hour played, the ball struck Trent Alexander-Arnold on the arm inside the box.

The referee consulted with VAR but ultimately the penalty was not given.

Watch the incident below:

Towards the end of the game, Liverpool could well have been reduced to 10 men after Mohamed Salah’s clumsy challenge.

Salah overran the ball and his studs made contact with Danilo’s shin.

Salah is a lucky boy there.

One man that has hinted his disapproval with both decisions is Iker Casillas.

The Porto goalkeeper posted images of both incidents on Twitter after the game.

Although he made no reference to the decisions, he’s obviously not too happy that the decisions went against his side.
