Pre-season football matches are not renowned for strong challenges and player disputes, though one friendly Liverpool were involved in three years ago certainly bucked this trend.
On the back of their Champions League triumph in Madrid, Jurgen Klopp's side flew out to America one month later to take part in games against Borussia Dortmund, Sevilla and Sporting Lisbon. A 3-2 defeat was the outcome in the Reds' opening fixture with Dortmund and a second loss followed the next day against the club's Spanish opponents.
The scoreline was the last thing on the mind of the Liverpool boss or his first-team players, however, as they fled Fenway Park in Boston after conceding a late goal which sealed a Sevilla win. Indeed, this contest had been significantly overshadowed by Joris Gnagnon's dangerous tackle on Yasser Larouci, which occurred with less than 15 minutes to play.
