Throughout this season, Inter have showed multiple times the strength of the team, the defense. This is also evident in the Europa League as Inter have one of the best defense in the competition.
In fact, the Nerazzurri have kept a clean sheet in the last 3 matches. The last time that the Nerazzurri did better in a single season (excluding preliminaries) dates back to 1991 when Inter did not concede a goal in five consecutive matches under Trapattoni which eventually led to Inter winning the UEFA Cup.
Inter is also one of the 5 clubs to not concede a goal in the Europa League 2018/19 knockout phase.
