In the absence of Harry Kane and Dele Alli, Son has been in great form since returning to the squad after the Asia Cup and continued his fine run into the first leg of this last-16 Champions League tie.

The defender, playing as a wing-back, then added one of his own in similar fashion, a volley from Serge Aurier’s deep cross.
