First off, give a single piece of evidence that any of those targets were for commercial reasons or that Mourinho didn't want them. Second and most important, it's stated by both 'insiders', all rumours, Levy/Woodward and seemingly everyone else that Levy/Poch point blank refused to sell Alder, in particular to a rival and that Woodward had a conversation about it and was given a price point that made the transfer non viable. IE, they said we don't want to sell him, the only way we would sell him to you right now is if you paid >100mil and Woodward correctly said okay that's the end of that then.
Same with Maguire, Mourinho wanted him, Leicester were contacted and they had no reason to sell nor wanted to and said okay, give us stupendous and stupid money and you can have him.
In what way was a club that never wanted to sell him and put an absurd price tag on him made him a 'very realistic target', in your make believe land of Mourinho could do no wrong and the world was against him.
I'll again point out that Mourinho had a rant only a few weeks back about how it's sooooo much harder for him than Fergie because when Fergie wanted Carrick and Berbatov Spurs sold, but now with all this money in the game when he wanted a Spurs player, Spurs refused. He left out the part where Spurs finished 11th the season before they sold Berbatov, and the season before Carrick was sold they finished 5th but iirc a fair way off and that was a one off stronger season. Right now they didn't sell to Utd because Spurs are a consistent top 4 team right now and they weren't close to one when they sold Berbatov.
So here in lies the point, if Spurs were willing to sell and the only hurdle was Woodward, why was Mourinho bemoaning Spurs being unwilling to sell Utd their players?
Boo hoo, Mourinho can't buy whatever player he wants like he could for Chelsea the first go round, mostly because he was buying from all over Europe.
Lastly, had they bought Maguire and Alder, he'd have made them play worse over the course of a season and into the following years because that is how almost all players went under Mourinho. So what did it matter anyway? Defence or lack of CBs can be a reason why you lose games due to defensive mistakes, it's not at all a reason why a team plays bad football, full stop. THey were rubbish upfront, in midfield and defence and it's not because Woodward wouldn't buy two 100mil CBs to help stop the rot that was the entire rest of the team.
