Watch: Salah's expulsion and penalty kick .. Did the referee injustice Porto?

The referees in Liverpool, Porto, Tottenham and Manchester City on the other side of the quarter-finals of the Champions League have become the main concern of the British press since yesterday.

The first of these cases was the mistake made by the Egyptian star Mohammed Salah ten minutes before the end of the match - which ended with the victory of the "Ridz" with two goals without a response - against the captain of the Portuguese team, Danilo Pereira, which was said to be a dangerous game and deserves the red card directly.

"I saw the incident and prepared it three or four times, and in my opinion that the intervention of Salah did not take into account the safety of the opponent and this entails the direct expulsion of the red card."

"Was he reckless and unintentional? It is possible, but the way Salah enters the player's foot indicates that he deserves the expulsion. The referee had to review the mouse's technique to make the right decision and unfortunately he did not."

Former England international Danny Mills said Salah "deserved the red card ... a dirty mistake ... he had to be fired."

Gamal Al-Sharif, an expert on the BBC Sports Channel, said that Salah did not put the safety of the opponent in the final account, and added that the Egyptian star was not deliberately harming the player.

On the subject of the touch of hand on the Liverpool player Alexander - Arnold inside the penalty area after a rebound from goalkeeper Alison Baker, compared the newspaper "Sun" British between the touch of "Arnold" and the touch that gave Manchester United a penalty in front of Paris St Germain in the second leg of the final of the tournament , And the touch of Tottenham defender Danny Rose in the face of Man City yesterday, which earned a penalty for the latter.

International referee Gamal El-Sherif says the penalty awarded to Man City was correct because Rose moved his hand up to repel Rahim Stirling's shot, while Lahouz was right when he did not give Porto a penalty because the ball bounced off the keeper and touched Alexander-Arnold in a different way. Intentional.
