Following Sunday's 1-1 draw at the Emirates Stadium between the two sides, the Spaniard claims the Premier League leaders faced their toughest domestic challenge so far this termMikel Arteta believes Everton are the best side Arsenal have faced in the Premier League this season.
Arsene Wenger’s side were on course to extend their lead at the top of the table to seven points following Mesut Ozil’s strike in the 80th minute but Roberto Martinez’s men snatched a point at the Emirates Stadium on Sunday following Gerard Deulofeu’s fine finish.
"It was a really tough game, a really high tempo game," said Arteta.
"They dominated the first 35 minutes or so but after that we had three clear chances.
"In the second half we were the better side. Everton are the best side we have faced this season in the Premier League.
"They have been getting results because they are doing things right. They have a good mix of players and are hard to deal with."
