Barkley, Cleverly, Naismith, Kone and McCarthy could likely all start against Watford. That's the spine of our attack and midfield.
Rom has a hamstring injury. We probably won't see him till the 3rd game of the season at the earliest.
Don't kid yourself. Our main problem last season was creating chances and this pre-season hasn't shown any reason to believe that is likely to change.
Bet you he plays tomorrow because he hasn't done anything to his hamstring.
