Keown feels his old side need a combination of new players and keeping the first team squad fully fit in order to close the gap on Chelsea next season.
“I think they need both of those things. If you don’t win the league, you are not good enough,” he said.
“Arsenal have been exceptional since Christmas but there are no prizes for that. There will always be question marks until the Premier League is won again.”
“Whoever does come in has to be a special type of player. They need to be a driving force and a proven winner that can make the difference.”
It’s unclear at the moment exactly where Arsene Wenger will look to sign new players over the summer.
There are positions where the Arsenal squad could use new bodies such as in the middle of the back four, out wide and at holding midfield, but the Frenchman is a manager who will not sign players unless they are better than the options he already has.
Arsenal have the resources needed to go after any high profile signing, but Wenger will also be looking to trim the fact and refine the squad that he already has.
In terms of fitness, injuries will accumulate over the course of a long season, which is unavoidable.
The Premier League and the Champions League are both high intensity competitions and it’s important the Gunners work hard through pre-season to give themselves the best possible chance of keeping their main players fit and injury free.
