Tottenham Hotspur's South Korean striker Son Heung-Min (R) celebrates scoring his team's fourth goal, and his second goal during the English Premier League football match between Tottenham Hotspur and Watford at White Hart Lane in London, on April 8, 2017.
Asked what most impressed him, the Tottenham manager said: "Wow".
"The message for us is to keep pushing, winning games", said the Argentinian, 45.
Three goals in 11 minutes, from Dele Alli, Eric Dier and Heung-Min Son, towards the end of the first half put them on top against a Watford side who had started brightly in the spring sunshine.
Well-organised Watford kept Spurs at arms length for the next dozen minutes or so, before Alli's moment of inspiration broke the deadlock.
After recovering from a goal down to win in the final two minutes of the mid-week trip to Swansea City, Spurs did everything that was asked of them against a poor Watford side with little still to play for this season.
Dele Alli added another dazzling entry to his showreel with a sublime opening goal in Tottenham Hotspur's 4-0 rout of Watford on Saturday as comparisons with England's so-called golden generation stacked up. "He is here because we believe in him and if Michael Vorm is not ready he is a keeper who can cope".
Tottenham breezed past Watford to provisionally move to within four points of league leaders Chelsea. By then, the score was already 4-0 mainly thanks to Son.

Jurgen Klopp has told his Liverpool stars to copy Chelsea's blueprint as they fight to qualify for the Champions League. But I see a player with energy, pace, good movement, a hard shot and an ability to score goals with his head.
Walter Mazzarri's side stay 10th and remain on the cusp of securing their Premier League status as they are nine points above the drop zone with seven games remaining.
With fit-again leading scorer Harry Kane sunning himself on the bench as one of Tottenham's substitutes, Dutchman Vincent Janssen was given a rare chance to impress.
Son's cross from the left deflects into his path and the midfielder thunders a rasping drive home from the edge of the box.
Spurs have been on a fantastic run of form, winning six matches in a row in all competitions, and winning seven of their last ten Premier League matches.
Amid the barrage, including a second for Son on 54 minutes, Janssen was the odd man out - standing at the saloon doors with his pistol holstered.
After 18, 20 minutes we read the game very well, started to control it, create a lot of chances.
For so long, Kane has been Tottenham's talisman and poster boy - the one player they can not do without - but they are unbeaten in eight league matches (five wins, three draws) without the England striker this season and they were 4-0 up before he came on.
Troy Deeney has scored against 41 different teams during his Watford career, but has never scored in four appearances against Spurs for the Hornets.
