Sorry mate but that is simply untrue. I would wager every singing made during his tenure, barring maybe Pogba, were players Mourinho specifically wanted. They were classic Mourinho players. They only refused to back him(rightly) last summer because every player he'd signed has regressed, and he wanted the likes of Toby and Perisic for close to 100 million who are both neigh on 30 years of age.
Make no mistake about it, they would 110% back Poch in the market and it will be one of their biggest selling points when/if they approach him.
There all big names but a lot of them where unproven players from foriegn leagues and Pogba and Miki both are not hard working something Mourinho always asks for.
I'm not disputing btw that Mourinho should do better with the squad he had, think he was making a point to the board about how unhappy he was and was wanting a massive payout.
Just think the people saying they will back Poch might be far off they haven't properly backed a manager under Woodward in a long time fully.
