Tottenham star Son Heung-min had to be taken off after clashing heads with Chancel Mbemba in the first half during the 2-1 win against Marseille.
The 30-year-old is now a doubt for the huge Premier League clash against Liverpool this weekend after he was substituted for Yves Bissouma in the 29th minute. Spurs are yet to find out the full extent of Son's injury, but it was clear to see that the forward was in discomfort as he exited the pitch.
Mbemba was able to continue and opened the scoring for the Ligue 1 side with a powerful header past Hugo Lloris on the stroke of half-time. Clement Lenglet brought the Lilywhites back level in France with a header of his own before a late strike from Pierre-Emile Hojbjerg sealed a dramatic comeback win for Spurs as they finished top of the group following a brilliant second half performance.

The 30-year-old has been pictured nursing a swollen eye as he celebrated with his teammates following the win against Marseille. Assistant manager Cristian Stellini, who took Antonio Conte's place on the touchline as the Italian served his ban for a red card received after the draw against Sporting, provided an update on Son's condition after the match.
“In this moment, we don't know,” he told reporters on Tuesday night. “We have to wait for a medical assessment, and we have to wait until tomorrow.
"Sonny feels better now. I saw him in the dressing room. He celebrated with us. So we will wait for tomorrow.
“We are not sure [if he was concussed]. It is his face. His eye is a bit swollen," he added.
It is unclear yet whether Son will be fit enough to start against Liverpool on Sunday afternoon, but Spurs will be hoping the swelling goes down quickly as they try to head into the World Cup break in the best form possible.
