With this victory, Inter Milan, chasing their fourth UEFA CL title and their first since the 2009-10 season, have beaten Barcelona by 7-6 on aggregate, after a 3-3 draw in their first match.

In the first half, Inter Milan had things very comfortable with a 2-0 lead. In the 21st minute, it was Lautaro Martinez who broke the deadlock. Just before the end of half-time, a penalty conversion from Hakan Calhanoglou doubled the lead for the hosts.
