- Gnagnon was shown a straight red card after sweeping one of the Frenchman's legs out from underneath him, toppling him to the pitch where his head bounced hard on the ground
- Even with the La Liga outfit reduced to 10 men, Liverpool were unable find a way ahead
- Nolito's powerful shot in the 37th minute past Liverpool starting goalkeeper Andy Lonergan - who was at Middlesbrough last season - was Sevilla's reward after a half-hour of pressure
Alejandro Pozo delivered the late dagger in 10-man Sevilla's 2-1 friendly win over Liverpool in Boston Sunday, a defeat made worse for the European champions when they saw Yasser Larouci stretchered off.
Liverpool manager Jurgen Klopp was furious at Joris Gagnon's outrageous kick at an on-rushing Larouci in the 76th minute. Gnagnon was shown a straight red card after sweeping one of the Frenchman's legs out from underneath him, toppling him to the pitch where his head bounced hard on the ground.
"(It's) much too early in the season to create headlines with saying the things I think about the situation," Klopp said at his post-match press conference, where he added that it appeared that the 18-year-old Larouci was "lucky" in terms of avoiding serious injury.
"But of course, how it always is with these things we have to wait a little bit. I don't know 100 percent. 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."
Even with the La Liga outfit reduced to 10 men, Liverpool were unable find a way ahead, and Pozo sealed it in the 90th minute as he smoothly collected a pass from Munir El Haddadi, rounded Liverpool keeper Simon Mignolet and knocked the winner into an unguarded net.
Sevilla had enjoyed by far the majority of scoring chances on a sweltering evening at Fenway Park - home of the World Series Champion Boston Red Sox. Both Liverpool and the Red Sox are owned by groups led by John W. Henry.
Players were granted water breaks in the hot, humid conditions, and even the pitch created on the baseball diamond received extra water during the match.
