Tottenham beat Manchester City 2-1 on Sunday afternoon - here are five talking points from the game.
Full back rotation works wonders again
Much has been made of Mauricio Pochettino's decision to rotate his full backs this season. Kyle Walker and Kieran Trippier have been fighting for one spot at right back, whilst it's been Danny Rose and Ben Davies competing on the other side.
Against Manchester City, Pochettino went with Walker and Rose; a decision which paid off. Both players were excellent at the Etihad Stadium, with Rose particularly impressing. All four players are fighting for places and performing superbly when they get their chance, and Pochettino deserves great praise for that situation.
Lamela makes a huge impact
As well as the competition at full back, Pochettino also has a host of players fighting for a role on the right hand side of midfielder. Son Heung-min, Erik Lamela and Nacer Chadli have all been given a chance there, but it was Son who started against City, with the South Korean international putting in a tireless performance before being substituted.
Later in the game, Lamela came on and ultimately changed the game. The Argentine offered a counter-attacking threat whilst City put the pressure on the Spurs goal, and his driving run at the City defence ended in a superb pass to Christian Eriksen to score the winning goal. This was a substitution which couldn't have gone much better for Pochettino.
Spurs were somewhat fortunate, but Pochettino deserved the win for being bold
The penalty which Harry Kane scored to make it 1-0 to Spurs was highly contentious; the ball appears to strike Raheem Sterling's armpit rather than his hand, and in many other games, Spurs wouldn't have got that decision.
But, they say that fortune favours the brave, and that's what Pochettino was. He didn't fear City even in their own back yard, and played an attacking line-up with Son Heung-min, Dele Alli, Christian Eriksen and Harry Kane all starting, whilst Pochettino also pushed for the win by bringing Lamela on. Pochettino was bold, and got his rewards for that.
Some key players were quiet, but came up big when they were needed
Most Spurs fans will admit that they have seen the likes of Alli, Eriksen and Kane perform better this season. The trio were decent against City, but didn't quite have the impact that Pochettino would have wanted from his big-name players.
Ultimately though, when they were called upon, they delivered; Kane stuck away the penalty with supreme confidence to put Tottenham ahead, before Eriksen kept his composure to beat Joe Hart and win the game late on. Whilst Pochettino would want those players to be in top form throughout, having them come up in big moments is what can be the difference between a draw and a win - and that's vital for a title challenger.
If you didn't think Tottenham were serious title contenders, you do now
Some fans and even pundits still couldn't really buy Tottenham as a title challenger. 'They're Spurs, they'll collapse', was the line used even when Spurs were flying. Now, there can be no doubt: Tottenham would be a deserving Premier League champion.
With the league's best defence and some exciting attacking football along with with a relentless pressing game, Spurs have everything it takes to win the title. Even having lost their 1-0 lead at the Etihad Stadium, Spurs didn't let their heads drop in the face of intense City pressure, and even came back to win the game. They have resiliency that some may say is 'un-Spurs-like', but it could be their steel which brings home an unexpected Premier League crown come May.
