Spurs appeared to be heading for a 1-1 draw on Monday evening after in-form Watford striker Odion Ighalo cancelled out Erik Lamela’s brilliant opener.
However, summer signing Son came off the bench to back-heel a 90th-minute winner past former Spurs goalkeeper Heurelho Gomes at Vicarage Road.
Kane’s girlfriend Kate was seemingly at Watford for Monday’s clash and while the Spurs players jubilantly celebrated on the pitch in front of their supporters, Gooders posted a festive Tottenham chant on Twitter.
Jingle bells, jingle bells, jingle all the way, oh what fun it is to see Tottenham win away 🙊🎉⚽️👍🏽

Kane teed up Lamela for the north London side’s opener at Watford but the England striker was unable to add to his 11 Premier League goals this season.
Mauricio Pochettino’s side are three points behind Premier League leaders Arsenal ahead of their next game at Everton on 3 January 2016.
