I feel sorry for Martinez, I really do. Unless he hits the ground running he's going to get destroyed by sections of our "supporter" base and it won't be his fault. Maybe one of the reasons he's supposedly only 'considering' an offer is that he's seen the swathes of negativity amongst the LFC fans.
Personally I think it's too big a step for him too soon in his career. I do think he will be a successful manager and one day could possibly be one of the game's top managers - who knows, he may even work wonders for us, should he take the job. He's an unknown quantity at a higher level than Wigan though, which is the problem.
You'd like to think FSG have been advised by some people who really know the game. I'm not sure who they may be (though I've seen the rumours), but if they've suggested Martinez as their pick they must have one hell of a crystal ball. John Henry strikes me as a very intelligent, calm and resourceful man but he doesn't know football well enough to make these decisions - so I'd hope when he was asking for advice on the matter he'd be talking to 'football' people, although the quality of those differs wildly!
If Martinez takes this offer, then it's a huge gamble on FSG's part with their investment. As fans we can only support and hope it pays off...
