Liverpool's friendly against Sevilla was marred by a shocking challenge on Yasser Larouci that forced the Reds youngster to leave the field on a stretcher in Boston.

Jurgen Klopp's Liverpool suffered a late 2-1 loss to Sevilla, but Sunday's result was overshadowed by Joris Gnagnon's horrendous tackle on Larouci.

In a feisty game at Fenway Park, Sevilla substitute Gnagnon was shown a straight red card with 14 minutes remaining after wildly kicking out at Larouci.

Larouci required lengthy treatment before the 18-year-old was taken away on a stretcher as tempers flared in the United States.

Despite Sevilla's numerical disadvantage, Julen Lopetegui's LaLiga side were victorious thanks to Alejandro Pozo's 90th-minute winner.

It came after Divock Origi had cancelled out Nolito's opener on the stroke of half-time with an emphatic close-range finish.
