"We don't have to talk about top four today". Without Dembele or Wanyama, and with Eric Dier on the bench, the away fans would have been licking their lips at the prospect of their fearsome front three escaping the likes of Winks and Alli but both showed a positional awareness that ensured Spurs' defenders were rarely overloaded compared to their counterparts.
Up against a Spurs side that boasted the best defensive record in the Premier League last season yet still spent big to bolster their options, Liverpool's lack of activity in that regard was brought into even greater focus.
Kane netted one more in the second half, as Jurgen Klopp's men struggled to deal with their intensity and superiority.
Pochettino also revealed that his tactics in starting natural right-back Serge Aurier at left-back was to counter Mohamed Salah's pace.
But it was the home side who made a lightning start. It was Kane's 44th goal of 2017 for club and country, but his first at Wembley in the Premier League. Everyone knows about Harry Kane's goals, Christian Eriksen's assists and Dele Alli's ability to arrive late and score, but Heung-Min Son regularly goes unnoticed.
Liverpool were already wobbling.
Liverpool's defence parted again to allow Son in on goal soon afterwards but his ferocious effort struck the underside of the crossbar. Salah plays on the right with his left, always coming inside. Ben Woodburn has the ability to become Liverpool's next big star, with Trent Alexander-Arnold also having a chance, but nearly 20 years have passed since the likes of Steven Gerrard and Jamie Carragher emerged at Anfield, following on from Robbie Fowler and Michael Owen, and there has been little sign of local kids coming through since.
But just before the break Spurs added a third.
Liverpool began the second period brightly, but any thoughts of a comeback were exposed within ten minutes of the restart.
In the 56th minute, Mignolet flapped at Trippier's inswinging free kick, Jan Vertonghen's shot was cleared off the line by Roberto Firmino but it fell to the lurking Kane who steadied himself before drilling into the corner.
Liverpool pushed for a consolation and Lloris made two excellent saves to push a curling Philippe Coutinho shot onto the post and deny Salah a second with his legs.
