I mean, it's at least an option on the bench. He knew that Ugarte wasn't fit. He basically said he might take a month to get up to speed with no preseason. But he's left it to a kid who barely shaves.
We also can talk about Liverpool having better players and that's true, but walking in after a legend (ETH did not), where the doors were starting to come off of the wagon, is a pretty stiff job for anyone. Certainly more than ETH could have done. If anything, ETH has had more money and room to do a lot, along with a built in, it's not his fault level that basically ANY other manger would not get. Spent a zillion dollars on shitty Dutch league players? Nope, not his fault, shitty owners. Players he does have? Not his fault, didn't get them. Hell, his best players on the squad by far are a kid who can't buy beer in the USA and Bruno, who was what? 3 managers ago? ETH showing a team on the up, playing consistently, with a system, playing in 3-4th, with some progress would probably be good enough to justify. But he has inmates running the asylum and looks like he has no plan.
It's a complete joke that anyone would defend him.
The only reason he's manager is because United weren't able to get someone they would have wanted more (because many people don't want the job) and because they don't have the stones to pull the trigger yet when he 'won a trophy or two'.
