Inter Milan substitute Davide Frattesi struck an extra-time winner to send his side into the Champions League final following a barnstorming 4-3 victory over Barcelona on Tuesday after Francesco Acerbi had rescued them from the brink of elimination with a stunning equaliser deep in added time.

Frattesi’s goal secured Inter a rip-roaring 7-6 aggregate victory in a semi-final for the ages that finished up with the Italian side reaching the Munich final where they will face either Paris St Germain or Arsenal later this month.

Inter dominated the first half and took a two-goal lead through a counter goal from Lautaro Martinez in the 21st minute, followed by a penalty kick from Hakan Calhanoglu just before halftime.

However, Barca came alive in the second half, with goals from Eric Garcia and Dani Olmo within six minutes to tie the score, and after Inter custodian Yann Sommer made a series of saves to keep the home team alive, the Catalans believed they had won through a close-range goal from Raphinha in the 87th

Denzel Dumfries found 37-year-old Acerbi inside the box during Inter’s desperate attempt to equalise, and he sent a first-time shot into the goal to score his first European goal in his 20th season and force extra time.

Frattesi set himself up and skilfully guided a curling shot into the bottom corner to send the ecstatic home crowd into raptures after Marcus Thuram’s incredible run from the right and play of the ball into the area in the 99th minute.
