I think we'd have more than enough games in a season to keep both Drogba and Carroll happy. Kuyt and Suarez will anyway end up playing a lot as wing forwards, so I don't think we should worry about how we can accommodate in him in the team. Ideally, I'd have wanted someone like Benzema coming in as competition for Carroll for the central striking role (and also to offer a different type of option), but if you get the chance to sign someone like Drogba, you don't miss it, even if he's 33.
I'd be pretty excited if this happens. Add a quality winger (Young would do) to the mix, and things could look very exciting for next season.
