Eric Dier and Son Heung-min quickly added two goals to pile the misery on Watford, putting them 3-0 behind at half-time.
The Spurs youngster is now the highest scoring midfielder in the league this season and Lampard, who holds the record for most Premier League goals by a midfielder, had nothing but praise for him.
A successful afternoon for Spurs was capped by the return of England striker Harry Kane after injury but Argentinian boss Pochettino was convinced his squad had already shown they were strong enough to cope with the loss of a key player.
Antonio Conte's Blues face a tricky away trip to Bournemouth in today's late kick-off and the Italian is sure to be feeling just a little uncomfortable after watching another Tottenham masterclass.

"We'll see whether he will start the game or be on the bench", the Argentinean continued, in reference to the likelihood of Kane being in the starting lineup in Spurs' upcoming match against Watford on Saturday. "It's important that we compete against us", he told Sky Sports.
Spurs are the only opponent the Hornets have played in all four of their Premier League seasons without winning.
"Whenever I got the nod from the manager, whoever we're playing against, I try to perform well for the team".
Or course, with the form Chelsea are in it is hard to imagine that they themselves will relinquish their grip on the top, but with the right additions over the summer Spurs could maintain a more meaningful title challenge next season.
Tottenham, who also hit the crossbar three times, were never likely to suffer defeat against a Watford side plagued by injuries as Walter Mazzarri shuffled his pack with Troy Deeney only on the bench due to fatigue.
"We keep pushing. We're in a very good position, second in the table and now we'll go home, be calm and watch the game!" he said, referring to Chelsea's late kickoff at Bournemouth. They want to be an established top team in the league, and Pochettino is well on his way to make Tottenham a true title contender. These are young men taking responsibility, they are winners.
The 26-year-old was a surprise inclusion for Spurs as they eased past Watford on Saturday, and he proved to be one of the best players on the pitch in the 4-0 win.
