Tottenham Hotspur made sure they claimed top spot in the Premier League heading into the international break after Son Heung-min scored the only goal of the game in a win over Watford on Sunday.
Nuno Espirito Santo's side have made a flawless start to the new domestic season and they sit two points clear of second placed West Ham United after a third successive 1-0 victory.
Son settled a hard-fought clash at the Tottenham Hotspur Stadium when his free-kick caught Watford goalkeeper Daniel Bachmann out of position in the 42nd minute.
After their protracted search for a manager to succeed to Jose Mourinho dragged on throughout the close-season, Tottenham were in danger of becoming a laughing stock.
Nuno was far from their first choice, but the former Wolves manager has hit the ground running north London.
Three consecutive wins, including against Premier League champions Manchester City, as well as progress in the Europa Conference League, suggest Tottenham could enjoy a better season than expected.
It will help that Harry Kane remains in the fold and the striker was making his first league of the season after the end of his transfer saga.
The England captain's future was resolved this week when he announced he was staying at the club after failing in his attempt to force a move to Manchester City.
Kane's name was loudly cheered by the Tottenham fans before kick-off and he had a strong penalty appeal turned down in opening minute.
Watford midfielder Moussa Sissoko was back at Tottenham, just two days after leaving for the Hornets and he nearly laid on an early goal. Sissoko picked out Juraj Kucka and his shot was headed off the line by Eric Dier.
Bachmann made a good save to repel Japhet Tanganga's close-range effort after the Hornets failed to clear a corner.
Son shot wide and Davinson Sanchez headed over before Tottenham took the lead in the 42nd minute.
Son swung in a free-kick from the left wing and Bachmann was caught out as it sailed past him and the rest of the Watford defence into the far corner.
It was Son's second goal of the season after the forward's winner against Manchester City on the opening weekend.
Set up by Kane's pass, Dele Alli should have doubled the lead, but the midfielder swept just wide from close-range.
Kane was denied by Bachmann's fine save in the closing stages but Tottenham had done enough.
Leeds score late to draw at Burnley
In Sunday's other early match, Patrick Bamford rescued a 1-1 draw for Leeds United against Burnley at Turf Moor.
Sean Dyche's side took the lead in the 61st minute when Leeds failed to clear a corner and Matt Lowton's shot was flicked in by Chris Wood from six yards.
The New Zealand international's first goal of the season was the 30,000th scored in the Premier League era.
But Leed striker Bamford celebrated his first call-up to the England squad this week with the 86th minute equaliser.
Jamie Shackleton's shot was deflected into Bamford's path and he tapped in for his first goal this season.
Both Leeds and Burnley remain without a win in the league so far this term.
