Arsenal manager, Mikel Arteta has admitted his team made mistakes in their 2-1 defeat to Lens in the Champions League on Tuesday night.
It was the first defeat for the Gunners in all competitions this season.
“They are a really good side, exceptional opponent. We took the lead and then in one action they managed to score. We had a big chance straight after the break.
“In many occasions we attacked the space – but it was [decided] in the boxes. We missed some big chances and didn’t defend well enough for their goals.
“Mistakes happen in football and they will continue to be there somehow but the difference was made in both boxes. You have to put the ball in the back of the net and defend well.
“It was a big night for us. We weren’t able to take the result we wanted but we were able to learn,” Arteta told BBC.
Arsenal took the lead through Gabriel Jesus, but were pegged back by Adrien Thomasson’s equaliser after David Raya’s poor pass out the back.
Mikel Arteta’s men, who looked off-colour, failed to generate too many clear-cut chances and were made to pay when Sepe Wahi steered home the winner for Lens with just over 20 minutes to go.
