Arsenal won the league last season in part because of their excellent defence.

The Gunners conceded the fewest goals in the league but have already conceded five in six games.

The partnership of Gabriel Magalhaes and William Saliba is one of the best in the world and Arsenal look to be missing the injured Frenchman’s calmness.

Ezri Konsa was brought in from Aston Villa for £55m and, despite his quality, is still getting used to his new surroundings.

Left-back Calafiori, though, has proved integral to Arsenal‘s attacking threat. His equaliser against Leeds was his first league strike this term but no defender has been involved in more Premier League goals than the Italian (one goal, two assists).

“The last time we put our shirts on, something was missing.” added Arteta.

“And we need to be very conscious of that. From being exceptional and being the champions to being extremely average, like in that game, is a really thin line.

“So if you don’t want it more than the opponent, you are not able to cope emotionally with certain situations, you’re going to suffer.

“And we all suffered and we didn’t enjoy that game, but then you have to learn the lesson and we certainly done that.

“We speak about it and you could sense that there was something in those tummies.”
