Inter Milan striker Lautaro Martinez appeared to be frustrated with team-mate Alexis Sanchez after the match against Liverpool.
The Reds progressed to the Champions League quarter-finals despite losing 1-0 to the Serie A outfit on the night.
Jurgen Klopp’s side won the tie 2-1 on aggregate, following a 2-0 victory at the San Siro, but faced a nervy end to the second leg at Anfield thanks to Martinez’s goal.
