Tough to find a "good" best XI from lot. Options on the wing for example Trez, El Ghazi, Jota...Vassilev? Slim pickings. Rotating players like that isn't the worst thing IMO.
Not that you've said it but a lot of posts recently saying Smith hasn't improved players. Is there any universe any of those players can ever be "good" PL players? Vass maybe as he's so untested? The others no chance. You have to have decent base. Otherwise Liverpool and City would buy league two players for £50k a pop and let their world class managers turn them into world beaters.
I'd look to replace Smith if we stay up. I think with a record of one promotion from two thirds of a season in charge he's not a bad bet if we go down.
Open to options if you think there's any outstanding candidates though? Makes sense to give a new guy a season to bed in, while hopefully winning promotion. I know some people don't like him but if there was a Bielsa type (established top level coach) figure willing, I'd be up for it because it does look like Smith is short in the PL.
My worry with a lot of young managers is they could get swept away by the relentlessness of the Championship. The quality isn't all that but the slog is very real and it's tough.
If Suso stays it doesn't matter who's in charge because they're going to have shit players to work with. I'd sack him tonight if it was up to me.
