Martinez probably hasn't been scouting much while at Wigan with the limited funds he had or has been scouting different quality players in his time at Wigan/Swansea. Therefore the players he spent scouting then obviously aren't good enough for Everton now.
He's had two months in his new job, and he's had to teach the squad his style, learn more about the people he's working with. It's not just the players but everyone at the club including the physios, the groundsmen etc. With the limited time he's had, he's really just gone for the quality wigan players to make sure the players he's got perform immediately for Everton. Sure most Everton fans probably expected more than 4 ex wigan players but he's brought in delofeu, lukaku and he's using barkley in the first team, so he's not afraid to give youth a go, which was what everyone was crying out about last year. And while we can't keep delofeu/lukaku, if we can show other clubs this is a great place to send youth, then we will continue to get regular youngsters.
Personally I thought Moyes really screwed us over - especially when he was told to keep his hands off our players and that none of them was for sale. For someone who supposedly holds himself with the highest integrity, it was particularly hypocritical. I thought maybe at one stage that he may not have been looking after the transfers, but the dithering at the end left me no doubt moyesie had a part to play in their utter embarrasment of a transfer window. And seriously apparently Ozil wanted to go to Man U and Man U weren't interested. Ridiculous.
Also I'd rather we had kept fellaini but the fella wanted to leave in the end, so taking the 28m is not a bad thing. Felli is difficult to replace and one of a kind with his height and technical skill. Probably overpaid for McCarthy though I don't know enough about him to say. For once though I would really like Everton to blow a ****load of money on a striker like hulk, aguero, falcao, not that they would come, soldado was only 25m (even if he's looked ****house so far) so to be honest not really that expensive in this day and age...
And finally ppl need to get a grip on the results, yes its been three draws, but liverpool have only scored 1 more goal than us in three games, and we conceded 2 more... man united haven't played well either.
