Son started the 1-1 draw in the first leg but was left out of the squad for Tottenham's 4-2 defeat against Wolves on Sunday.

Last week's first leg, in which Pedro Porro's brilliant flick cancelled out Hugo Ekitike's early strike, suggested Spurs have more than enough quality to beat the 2022 winners, even without Son, and has raised the possibility that Postecoglou's side could put their dreadful league form behind and go all the way in the competition.

However, he was replaced against Frankfurt. The coach's decision was entirely justified because he did not have a significant impact on the game. Son Heung-min doesn't look as sharp as he used to be.There is no doubt that Son Heung-min is a legend of Tottenham.
