He'll have his targets.
To be fair, you can look at
Moyes' signings and say wow, Cahill, Arteta, Martyn were all amazing buys, and then you can pick faults.
Then you can look at Martinez' at Wigan, and say well McCarthy, Al Habsi, Kone, Moses and Di Santo were all big signings for someone of Wigan's calibre. Whereas others like Boselli were disasterous.
So far We've had McCarthy, Deulofeu, Barry, and Lukaku who've been amazing. We've got a future signing in Joel and if you want to write of Kone as a disaster, then so be it. But with the bigger club like Everton, the calibre of player goes up, and i thoroughly expect any signing Bobby makes to be a good, well thought out one, and i'd be very surprised if he doesn't have someone ready to sign from Spain come January.
