Unai Emery finally got his first Premier League points on Sunday as Arsenal overcame West Ham.

But his side did not make it easy at all.

The Gunners went into the game at the Emirates Stadium as heavy favourites, but went 1-0 down after Marko Arnautovic broke the deadlock with 25 minutes played.

Nacho Monreal quickly levelled proceedings, before an own goal from Issa Diop, and a last minute goal from Danny Welbeck, gave Arsenal the victory.

It was a satisfactory result for Emery, but he would perhaps not be happy with the performance.

His side only conceded once, but in reality West Ham could have notched a few more.

Alan Shearer was working as a pundit on Match of the Day, and he nailed his take on Arsenal's performance.

The former England striker explained how he felt sorry for Arsenal's centre-backs, with their full-backs and midfield giving them very little protection.

After raving about Arsenal's full-bakcs in attack, he then turned to criticising them for their defensive duties.

“Conceding goals, if they continue to play like this and they don’t find the right balance, will be a huge problem,” he said on Match of the Day, per the Daily Star.

“And I feel sorry at times for the two centre-halves because they’ve got no protection whatsoever.

“Whether that’s in front of them or the other side of them.

“They really need midfielders to track runners as well because there’s not a lot of pace in that backline.

“Something has to change. They need protection in front of them and both full-backs can’t go forward at the same time.

“Otherwise they’ll get done time and time again.

“They’ve conceded two to Man City, three to Chelsea and it could have been four or five today.”

Spot on, Alan. The first three games have been promising for Arsenal, despite the fact they only have three points.

Emery has got his side playing some good football, and they constantly look a threat in attack.

But their defence is a real issue. They've already conceded six goals so far this season, but in reality it could have been a lot more.

And it's not necessarily because of a lack of quality; it's because their side is too attacking minded at the moment.

It's vital Emery addresses this problem soon, otherwise their hopes of a top four finish could quickly dissipate.
