Sevilla’s Joris Gnagnon has apologised for his “odious” foul on Liverpool’s Yasser Larouci, which forced the Liverpool youngster to be stretchered off the pitch during a pre-season friendly in Boston. Sevilla went on to win the match 2-1 thanks to a late Alejandro Pozo goal.

Jürgen Klopp later said it appeared Larouci had been “lucky” not to have suffered a more serious injury after he was forced off the field in the 80th minute. The 18-year-old left-back will need further assessment.

“It looks like he was lucky,” Klopp said at his post-match press conference. “Of course, how it always is with these things we have to wait a little bit.”

Joris Gnagnon was immediately shown a red card for the kick to Larouci’s leg while the scores were level at 1-1.

Asked for specifics on Larouci’s injury, Klopp added: “He hit him full throttle and, in that moment, [if it was] a little bit different position where he hit him then it’s done. He rolls … he is a sports boy so that was OK, nothing happened there.

“I don’t know 100%. It looks like he was lucky but I only spoke quickly to the doc and that’s what he said, but we have to see.”

After the match, Gnagnon apologised for the “odious” tackle. In a post on Twitter, he said: “I would like to publicly apologise towards Liverpool, the family of the player and its supporters. It was an odious act on my part. Whatever the reason, it’s not what should be seen on a football pitch. All my prayers are with the player and his family.”
