James Milner was scathing of Joris Gnagnon's "disgraceful" challenge on Yasser Larouci that marred the friendly between Liverpool and Sevilla.
Gnagnon was shown a straight red card for a horrendous tackle on Liverpool teenager Larouci, who was forced to leave the field on a stretcher in Sunday's 2-1 loss to Sevilla.
Sevilla defender and second-half substitute Gnagnon wildly kicked out at the 18-year-old with 14 minutes remaining in Boston, where tempers flared.
Gnagnon apologised post-match but Milner told LFCTV: "Was it too much? I thought so yes, it was a disgraceful tackle.
Jürgen Klopp has provided an update on Yasser Larouci.

"We know it's only a friendly, but I mean, you don't see many red cards in friendlies, do you?
"Their guy said it is down to the referee and it's a tackle and a foul, but it's very disappointing. We [responded] in the right way.
"It is a tough one for the referee because you don't want to use red cards in friendlies and it is a rare thing to see.
"It's not easy to get hold of the game, you don't normally see too many tackles [like Gnagnon's] but it is a disgrace really."
Larouci reportedly left Fenway Park on crutches after Jurgen Klopp's Liverpool succumbed to Alejandro Pozo's 90th-minute winner.
