The Koeman and Moyes comparison is somewhat short sighted. Just because Koeman has finished in the top 7 for two consecutive years with an unfashionable club doesn't mean he's anything like Moyes who showed over the course of about a decade that he couldn't take Everton any further than that.
Besides, Koeman already has wins away to Chelsea, Man United and Arsenal under his belt.
How is it when what i am saying is complete clear fact, that many of you cannot see it?
Moyes - Turns teams into plucky mid table also rans.
Koeman - fails in a big job (although i grant Ajax comes with pressure),wins mediocre leagues and developed 'plucky' Southampton.
= Clear paralells
Walter Smith - Got the job based on winning a mediocre league with Rangers.
Koeman - Won mediocre leagues, failed at Valencia when the standard was higher.
