Sevilla head coach Julen Lopetegui said Joris Gnagnon was "very, very worried" after his horror challenge left Liverpool teenager Yasser Larouci on a stretcher.
Sundays friendly in Boston — won 2-1 by Sevilla — was marred by Gnagnon wildly kicking out at 18-year-old Liverpool left-back Larouci. Sevilla defender and second-half substitute Gnagnon, who issued an apology post-game, was shown a straight red card with 14 minutes remaining, while Larouci required lengthy treatment at Fenway Park.
"[Gnagnon] was very, very worried and knows it could have been a bad injury," Lopetegui said.
"I am worried about the player [Larouci] but I asked Jurgen [Klopp] and he said the player is okay, it isnt a bad injury and I am happy for that. Thats the most important thing. The referee thought it was a red card and I havent seen a replay but its possible it was a red card."
Larouci reportedly left the stadium on crutches following a fiercely contested pre-season fixture, with Liverpool on the receiving end of some tough tackles.
Liverpool star Virgil van Dijk was infuriated by Gnagnons actions and he added: "I saw it from the side and its not nice. Especially when it happens against a young guy who is playing pretty well this season, its not great to see. I think it says something about him [Gnagnon]."
