Arsenal came from 2-0 down to rescue a point against Everton at Goodison Park on Saturday evening, with goals from Aaron Ramsey and Olivier Giroud grabbing a share of the spoils.
A disastrous first half showing from the Gunners saw Seamus Coleman and Steven Naismith put Roberto Martinez's side in cruise control at half time, but Ramsey met Santi Cazorla's cross to give the travelling Arsenal fans hope of a late fightback with just seven minutes to play.
Giroud then met Nacho Monreal's cross to steer a header past Tim Howard in the 90th minute, as Arsenal showed fight, guts and determination to haul themselves back into a game that seemed past them at half time. Here, we take a look at five things we learned from the match.
Mesut Ozil shouldn't play on the left
Arsene Wenger made the bold call to start Mesut Ozil on the left hand side of midfield against the Toffees, and it was an experiment that didn't pay off. The German struggled to influence the game and couldn't cope with Seamus Coleman's runs forward from right back, which ultimately led to the opening goal.
Arsene Wenger will admit when he's wrong
Wenger is often criticised for being stubborn, both in terms of his approach on the pitch and how he conducts his transfer business. However, today he released his mistakes at half time and rectified them by bringing on Olivier Giroud, and it led to a much improve Arsenal display.
Alexis Sanchez shouldn't play up front on his own
Not away from home, at least. The Chilean had just 26 touches as he cut a forlorn figure up front on his own. Away from home, a lone striker should be able to hold the ball up and play as a focal point - something Sanchez couldn't do, but something Giroud could; hence his impact when he came on.
Arsenal still struggle to handle Romelu Lukaku
Prior to the game, Wenger believed that Calum Chambers - a right back by nature - would handle Romelu Lukaku when playing at centre back. Whilst it wasn't even Lukaku's best display for Everton, he once again troubled the Arsenal back line with his power and pace. He tore them apart at Goodison Park last season, and played a huge part in Everton's first half success by shrugging off Per Mertesacker on his way to setting up Steven Naismith's goal.
Jack Wilshere continues to disappoint
Midfielder Wilshere has come in for plenty of criticism of late, and didn't do his case much good against Everton. As has been the case for some time now, Wilshere displayed plenty of effort and ultimately wasted energy, as he often wasted possession, offered little going forward and couldn't stop James McCarthy and Gareth Barry dictating the play in the first half.
