Arsenal manager, Mikel Arteta, has admitted their 1-1 draw with Chelsea in the Premier League on Sunday, was a tricky game to play.
The Gunners failed to extend their lead at the top of the table to seven points with the result at Stamford Bridge.
Although the Blues went down to 10 men following Moises Caicedos red card in the first half, they took the lead through Trevor Chalobah after the break.
