I'd tend to agree. I've been saying the exact same thing about that no.10/third midfielder position as well.
Pogba is straight back into the team regardless of if he is leaving in the Summer IMO, simply because next season, it won't be Andreas/Lingard/Mata who is first choice there. We might as well use Pogba there and hope he's at it, as he'd offer more than those players. When we're pretty much 99% bringing in a new player who's expected to start every important game, it doesn't matter who plays the position in the mean time as it won't effect the overall formula much. If anything, one of Mata/Andreas may be forced out as well.
As for Jones, I think it's long overdue that he leaves, hopefully we can find a buyer at a similar price we get for Smalling (I am assuming Smalling & Sanchez deals will be finalised next month). We could be in the market for another CB in the Summer though, as I'm not quite sure if Rojo/Bailly can stay fit enough to provide cover and give us the option to rest players in the less important games.
