I'm not saying he's not doing a decent job. If not a pos. net spend, he has had money to spend though and he hasn't spent it that well. Losing N'Zogbia wasn't the end of the world for them and he had opportunity to put it right. Moyes has done it time and time again. Buy someone cheap, sell them for big bucks and replace them with a fraction of that fee and turn them into a top class player thus repeating the cycle. e.g. Lescott to Heitinga. Moyes is doing this and is only treading water with us. You know Martinez won't have the success Moyes has had in the transfer market so the only way is down.
I know Martinez won't have the success in the transfer market AT WIGAN. At Everton would be a completely different story.
Moyes doesn't go all over the world watching these transfers train every day, he relies on scouts just like many other managers. Common sense would tell you that Wigan's scouting network isn't as good as Everton's is, so judging Martinez in that way isn't really fair.
Having said that, Victor Moses, Gary Caldwell and Di Santo have all been great transfers for a total cost of £5m. He's no dummy when it comes to transfer spending.
