Aaron Mooy's Huddersfield Town were left celebrating wildly after securing their Premier League safety on Wednesday with a dramatic and resilient 1-1 draw at Chelsea, a result that looks almost certain to condemn Swansea City to relegation.

With a Harry Kane goal giving Tottenham Hotspur a 1-0 win over Newcastle United at Wembley to secure their Champions League place for next season, Chelsea's draw may also have caused fatal damage to the Blues' hopes of a top-four finish.

Huddersfield, who needed a point to be sure of avoiding relegation, took a shock lead in the 50th minute when a long ball from Mooy found Laurent Depoitre who won a challenge with Chelsea goalkeeper Willy Caballero on the edge of the box and put the ball in the empty net.
