Arsenal fans suffered a 2-1 defeat against Everton on Tuesday night – and Chelsea supporters were thrilled with the result on Twitter.

The Gunners had the opportunity to move above Chelsea to the top of the Premier League with a win, but suffered their first league defeat since the opening day of the season.

Alexis Sanchez set Arsenal on the road to three points with a deflected free-kick goal, but Everton defender Seamus Coleman equalised just before half-time with a composed header.

Ashley Williams then scored an 86th minute winner from a corner and the Toffees survived a late Arsenal attack to secure the three points at Goodison Park.

Chelsea remain three points above Arsenal as a result and could move six points clear at the top of the table if they beat Sunderland away on Wednesday.

The Blues fans were extremely pleased with Arsenal’s loss and are now focused on extending their lead at the league’s summit.

Here is a selection of their messages on Twitter:

Chelsea are currently on a nine-game winning run in the league since Antonio switched to a 3-4-3 formation after a 3-0 defeat to Arsenal in September.

The Gunners are considered as one of the main contenders for the league title this season and the Blues have emerged as frontrunners after a spectacular turn of form.

Chelsea came through a tight encounter with West Brom 1-0 in their last game and will expect a similar match against a resilient Sunderland.

David Moyes’ side are currently bottom of the league table, but have won their last two games and could move out of the relegation places with a win.

In the latest Chelsea news, Stan Collymore has slammed the club’s first teamer as a disgrace.
