The referee elbowed the Liverpool defender to escape the penalty

"We have thoroughly reviewed all evidence regarding the recent incident at Anfield involving the Liverpool defender and the referee, and will take no further action," the statement said. The English Football Federation (FA) has a paragraph.

The FA said it had carefully reviewed detailed notices from Liverpool and the British Professional Arbitration Body (PGMOL), various angles of video footage and the circumstances involved.

Through PGMOL, Hatzidakis said she had "open and positive conversations" with Robertson. The line referee apologized to the Liverpool defender and expressed his desire to return to duty in the Premier League.

During halftime of Liverpool's match against Arsenal in the 30th round of the Premier League on April 9, when Robertson approached to talk, Hatzidakis suddenly elbowed the Liverpool defender in the face.

Referee Paul Tierney then upset the host by showing Robertson a yellow card for his reaction. Liverpool players surrounded the referee's team, in which captain Jordan Henderson pointed at Hatzidakis and accused him of hitting Robertson. Mohamed Salah tried to appease Robertson to avoid pushing the matter further. After the match, PGMOL announced that Hatzidakis was suspended until the FA finished the investigation.

According to British newspaper Sportmail, Hatzidakis spoke with PGMOL director Howard Webb on the evening of April 9. But this 38-year-old assistant referee is said to be "broken" by what has happened, and in the immediate future, will not be assigned a task in the 31st round of the Premier League this weekend.

There have been mixed opinions on the matter. After the match, coach Jurgen Klopp declined to comment, stressing that "the photos and videos say it all".

According to Keith Hackett - former director of PGMOL, Hatzidakis risks losing his entire career if convicted. Former striker Darren Bent said that Hatzidakis must be banned for eight matches like Aleksandar Mitrovic - the striker received a heavy penalty for pushing referee Chris Kavanagh in the match Fulham lost 0-2 to Man Utd in the quarter-finals of the FA Cup.

In contrast, former referee Mark Halsey defended Hatzidakis when he said that Robertson appeared to want to grab Hatzidakis, leading to a reaction of swiping hands and inadvertent collision. Similarly, former Man Utd captain Roy Keane said that Robertson used inappropriate words, and mocked the Liverpool defender as a "big kid".
