1. Dean Henderson 6
Relatively untroubled until a smart second-half stop to parry away Son's strike. Couldn't do anything about Son's goal, which also took a slight deflection off Basham Photo: Simon Bellis
2. George Baldock 8
Signalled his intentions in the first minute with a driving run which saw Dier booked and then scored the United equaliser with a cross-cum-shot that sent the travelling fans wild Photo: Danny Lawson
3. Chris Basham 7
Given a difficult time early on by Dele Alli but hardly put a foot wrong after that, before Alli was substituted in the second half. A superb challenge to deny Son with five minutes or so left Photo: Nathan Stirk
4. John Egan 7
Shook off a knock suffered against Burnley to start the game but played a part in Spurs' opener as he suffered a mix-up with his Irish mate Stevens. Kept Kane quiet Photo: Simon Bellis
