Depends, Moyes can develop players. If we're able to develop 5 Jags or 5 Lescott like players and sell them for the same amount of profit that is actually one of the few options we have of getting the club back on a healthier financial footing.
I actually think Moyes is capable of doing that too, and why he is one of our greatest assets.
Erm, to an extent yes. Moyes did very well to uncover Lescott and sell him at a high price and also has a history of finding bargains like Cahill and Arteta although I can't see us sell those two for a very good profit given their ages and in Arteta's case, his huge wage packet.
However, right now, if you look at the first team, I don't think Howard, Hibbert, Neville, Distin, Osman, Yakubu, Anichebe, Saha, Yobo, Mucha, Beckford and Cahill would command a good price tag (roughly £5m or more). So there is little value from selling those players although selling Yobo and Yakubu would free up the wage bill enormously and I could see us maybe receiving £7m in total for those 2 players.
Baines, Jagielka, Rodwell and Fellaini are considered our most valuable players as we believe we can pocket at least £15m from each individual sale, I have always accepted selling at least one of the latter two especially Rodwell but I fear that his 'promise' is fading as he had a poor season last time and Moyes doesn't seem to know his best position, will he really develop into a promising future England star? I wouldn't want to sell Baines or Jagielka right now, defence is the most important area as that has always been our foundation for getting results.
What is £10m Bilyaletdinov still doing at Everton? I think in future if money ever became available in vast amount (say we sell a player for £25m) then Moyes should refrain from spending big money, his history of signing expensive players is not very good and we can't afford to throw away money like that.
Another source of avenue of income is to develop the youngsters. We supposedly are supposed to have some promising players like Mustafi, Garbutt, Lundstram, Hope, Barkley, Vellios, Baxter, Gueye etc. But some including Gueye (ok he is injured now), Mustafi, Duffy, Vellios and Baxter have seen their opportunities extremely limited and because they are not playing enough games then their overall value cannot increase. Moyes has to give youngsters more opportunities in the future in order to a) replace departing experienced players and b) sell on for a very good price to another club.
