"We played very well for 55 minutes and then suddenly we were another team", Chelsea manager Maurizio Sarri said.
Alexandre Lacazette capitalised on a Marcos Rojo mistake in the second half only for Jesse Lingard to respond nearly immediately, meaning each side had to settle for a draw that does not greatly benefit their top-four ambitions.
"He was dragged off in a game before the World Cup started in a friendly and that set the tone, "you do what I ask you, or you ain't going to play".
"But it's nearly a different Arsenal side now, they're playing better football, they're a more aggressive team and looking at them now they're one of the strongest teams in the league".
Marcos Rojo upped the stakes, losing the ball inside his own half to allow Henrikh Mkhitaryan and Alexandre Lacazette clear.
But with his exciting skill, playmaker ability and his knack of scoring goals, the Spain global could be a real hit at The Emirates Stadium.

Manchester United were held to a 0-0 draw with Crystal Palace at Old Trafford last month before their stalemate on the south coast last weekend.
United fans don't need reminding of his worth, but De Gea did so anyway, producing contrasting saves to keep out Pierre-Emerick Aubameyang twice in the second half. Aaron Ramsey starts in an attacking midfield role while Matteo Guendouzi will play alongside Lucas Torreira.
Arsenal are next in action against Huddersfield Town at the Emirates on Saturday and Emery may well be tempted to rotate his side following a couple of bruising encounters over the last few days against Spurs and Manchester United. It's the 8-2; the Battle of Old Trafford; Giggsy's chest rug.
Arsenal's visit is the first of two home games in four days for United, who have won only three of their six Premier League fixtures at Old Trafford this season. Stick around, this promises to be must-watch blogging!
