Son has bagged 20 goals in all competitions this season, just one shy of a career high from the 2016-2017 season.

In the second leg, Son scored his two goals in a span of three minutes early in the wild first half. Rahim Sterling put Man City on the board in the fourth minute, and Son's two quick strikes, in the seventh and in the 10th minute, gave the Spurs a 2-1 lead.

Bernard Silva got the equalizer for City one minute later, and Sterling netted his second goal of the match in the 21st minute.

Sergio Aguero scored in the 59th minute to give Man City a 4-2 edge, which would have been enough to lift his club to the final four.

But Fernando Llorente's controversial goal in the 73rd minute, which was allowed to stand after a video review, gave the Spurs the crucial away goal.

Sterling appeared to have scored another to help Man City advance, but Aguero was ruled offside in a video review, and the goal was wiped out.

On a down note, Son will miss the first leg of the semifinals after picking up his third yellow card of the tournament early in the second half. He'd been cautioned twice during the group stage. (Yonhap)
