Sonny hit a couple of belters to make it 2-0 and 3-0 before a late, late volley crept through Lions goalkeeper Tom King to complete his first treble in Spurs colours. Christian Eriksen, who opened the scoring, Dele Alli and Vincent Janssen were also on target as we booked a place in the semi-final.
Sonny told us later
how that first Spurs matchball will provide motivation for future games as he took his tally to six in the FA Cup and 14 for the season.
Our fans certainly responded with a landslide vote in the MOTM as the South Korean star racked up 77% of the vote.
SPURS v MILLWALL - MAN OF THE MATCH
HEUNG-MIN SON - 77%
Christian Eriksen - 12%
Victor Wanyama- 6%
Dele Alli - 5%
Thanks as always for voting!
