Son Heung-Min scored two as Tottenham moved to within one victory of the Champions League round of 16 with a 4-0 victory over Red Star Belgrade on Wednesday.

Son was sent off for his involvement in an incident in which Eveton midfielder Andre Gomes suffered an horrific leg fracture on Sunday, but saw his red card later overturned, and was not expected to start this match, due to the emotional trauma following the accident.

However, he was named in Mauricio Pochettino's starting lineup and played a starring role with two goals in the Serbian capital.

Both sides missed early chances before Spurs eventually opened the scoring on 34 minutes after a comical goalmouth scramble which saw Tottenham hit the post and have an effort cleared off the line before Giovani Lo Celso -- making his first start for his new club -- headed home.

Son added a second on 57 minutes after he fired into the roof of the net from Dele Alli's pass. The South Korea international turned to the camera and made a praying sign, while appearing to apologise.

And he made it 3-0 three minutes later when he finished off from Danny Rose's square ball across the boss and again the celebrations were mooted. Christian Eriksen then squeezed in a fourth on 85 minutes.

The result leaves Tottenham second in Group B on seven points, with victory at home to Olympiakos in their next match enough to confirm their qualification to the round of 16.
