Yeah that's fair. For me I don't read too much into Martinez' comments - and not because it's Martinez saying them (which would be grounds alone to disregard the content) but because you simply wouldn't expect an intelligent businessman to come on board and do anything other than be perfectly nice to everyone he meets, from Roberto to the groundsman, and to not give off the slightest whiff that anyone's jobs are about to be lost.
His background is in business and he'll do what all incoming leaders do: come in, get the lay of the land, do his analysis of the situation, and make some decisions off the back of that. That process may take a couple months, it may take more. For me it lines up pretty nicely with the end of the season.
I personally wouldn't read much into him apparently offering Martinez his initial support or providing assurances about future funds. He's done exactly what you'd expect him to do regardless of how he may feel about the manager. If he'd come in and was already swinging his axe and putting people on edge, we'd have a much bigger issue on our hands.
Honestly, if we finish 9th or worse, I'd probably be surprised (and frankly disappointed) if he wasn't showing Martinez the door.
