Tottenham vs. Chelsea: Score and Reaction from 2017 Premier League Match

Chelsea fell to a surprise defeat in the Premier League at Tottenham Hotspur, as the north London club prevailed 2-0 at White Hart Lane on Wednesday.

Dele Alli opened the scoring for Spurs with an expertly taken header in stoppage time at the end of the first half. The England international claimed his brace after the restart for the second half, with the Blues struggling to find their recent quality.

Spurs were the better team on the night, and Chelsea manager Antonio Conte was baffled as he watched his side appear tired and weary.

Eric Dier, Toby Alderweireld and Jan Vertonghen anchored the hosts' defence with a back three, as Spurs attempted to stifle the attacking talents of Diego Costa and Eden Hazard.

Chelsea matched up against their opponents with a 3-4-3 formation of their own—one that has catapulted them to the top of the league in recent months.

The first half was largely a stalemate, as the Blues sat behind the ball, allowing Spurs to play their game in midfield.

It appeared the whistle would blow for half-time with no goals scored, but Tottenham broke the deadlock as Alli continued his improving form.

Christian Eriksen's masterful cross found the former MK Dons man in the box, and he directed his header past goalkeeper Thibaut Courtois with the precision of a world-class striker.

Sky Sports pundit Jamie Carragher lauded the player's finish:

Squawka Football highlighted Alli's amazing contribution to his team's cause:

Chelsea were out of the blocks quickly in the second half, and Costa lashed a vicious strike on goal, but stopper Hugo Lloris was equal to the effort.

Hazard should have equalised at the back post when the ball fell kindly to him, but the Belgian nodded his effort wide from close range.

Spurs attempted to play on the counter-attack as their wing-backs bombed forward, but Chelsea's play had significantly quickened in the chase for an equaliser.

However, Spurs doubled their lead after 53 minutes, playing out a carbon copy of their first strike. Eriksen was again the provider, swinging his cross towards the back post, and Alli again met the ball with his head to claim his brace.

The Premier League highlighted the midfielder's quality in the air:

Spurs continued to attack, looking comfortable as they pushed forward for a killer blow. 

Manager Mauricio Pochettino appeared to be delighted in the technical area as his team maintained control with a mature blend of passing and attacking.

The Blues continued to chase the game as Spurs controlled proceedings, and Eriksen almost capped off a fine display with a goal from a free-kick with 15 minutes remaining.

Chelsea appeared deflated in the closing moments, as the home fans roared from the stands in full approval.

Spurs had plenty of energy to keep the ball, and the league leaders had no answer to the task at hand.

Post-Match Reaction

Pochettino tipped his hat towards his goalscoring hero after the match and praised Alli's development, as quoted by Squawka Football:

Spurs are next in action on Sunday when they play host to Aston Villa in the FA Cup third round, while Chelsea entertain Peterborough United on the same day in their tie.
