All you can ask of Moshiri is that he backs the manager and does what he can behind the scenes to increase income and sort a stadium out. It sounds like he is trying to do this, it's not like going to the player shop and just picking one up! First I guess there needs to be an agreement between Walsh and Koeman to go for a certain player, there might be a few that we could have got but one or other didn't fancy them, then they make an enquiry and that club may or may not want to sell, then if we do get an agreement the player may or may not want to come to us. Players and agents can ask for more during negotiations and so on. It's not ludicrous to think we may have struggled to get in our top targets, remember both Koeman and Walsh turned up late in the summer. I expect them to have better back up planning this time around and have had time to properly assess our current squad.
Even if we had spent 150 million on players during the last window it still would be no guarantee that Moshiri is on the level, plenty have owners have spent piles of cash and when it didn't get them far they have retreated, (Newcastle and villa for starters) so I think he deserves at least open minds for the time being.
I think he has done enough already to deserve that, you have to be slightly unhinged to look at the whole situation, take in the facts and come to the conclusion he is just milking the club. This may be actually true, but just like we can't prove he did try to sign all these players, you can't say for sure he didn't and it was outside factors that prevented them from going through.
One things for sure we cannot keep on having transfer windows like the last one else we will start falling further from the top teams and our best players may try to force moves to other clubs.
