#2 Goalkeeping
Well, Bernd Leno appears to be a decent shot-stopper for the Gunners. Only God knows where they would be on the table without him. But, he looks jaded already. True, goal-keepers don’t have that much to do on the football pitch, but not the Gunners guardian.
The kind of clownish defense that is in front of him cannot be trusted. That is why poor Leno is always kept busy. That isn't very pressing but not having a backup that Arsenal can be confident in to stand in for him is the problem. As a saying goes, “Never overwork a good horse”. In Leno’s case, he is being overworked and burdened with saving the day for the Gunners at most times. Not having enough to show for his works must be killing him.
Look into the transfer market, get a good option at goal-keeping to deputise for Leno and see the lots of Gunners change for the better. Why David Ospina was sold in the first place is still something that is baffling. How can you sell someone decent when you don’t even have anyone to fill his shoes?
