"They return on Monday, train Monday, Tuesday, Wednesday and today so you can imagine that they are not really fit and ready", he said, although he was happy that Chilean Alexis Sanchez was raring to go after a full pre-season.
With a long list of alternative attacking options, it's unlikely that Welbeck will see too much action as a starter this season, but he poses to continue his valuable role from the bench.
Arsenal appointed Unai Emery as the new manager of the gunners in May and the Spanish worldwide has already started making a number of changes at a club which has been under the management of Arsene Wenger for two decades.
Unai Emery has been continually saying that he hopes to create his squad around Aaron Ramsey in nearly every public interview he is having but the player is still not ready to sign a new deal even though he is hearing such statements from the manager.
The French global was one of the most exciting players in Europe when he joined Barcelona in a big-money move from Borussia Dortmund last summer but he endured a frustrating debut campaign in Spain.
With the tactical prowess of Emery in sharp contrast to Arsene Wenger, his successor, you can expect the Gunners not to shy away from taking the game to Guardiola's men. I expect them back in the title.
Manchester City were nothing short of spectacular last season.
Last season's runaway champions provide the opposition at the Emirates Stadium as Arsenal begin a season without Frenchman Arsene Wenger in the dugout for the first time since 1996.
I am predicting a 2-1 win in favor of the Gunners.
