agree with most of what you say - except referencing CB’s age as a reason to get rid. It’s the fact that he doesn’t score goals that’s the reason we should offload him (and his wages).
I’d happily have an over 30 year old striker who scores 15 a season for 2 or 3 years!

Yes they have but we’re not alone. Every club including the big boys have a long list of players who have come in on big transfer fees and wages that haven’t worked out. It’s just one of those things.

Whatever happenned to the thought that it took 1 Season for a new player to bed in? I seem to remember regularly with a new player the 2nd season was always better -especially if they have to adjust culturally too.
nowadays new signings are expected to hit the ground sprinting.

Many of the clubs where purchases don't seem to work out have a disconnect between the manager and the person doing the recruitment. I can't imagine for one minute that Ferguson would have allowed the club to buy players that he didn't want and Newcastle is another club where the chairman's buddy buys the players whether Steve Bruce wants them or not.

I'm not sure how much of an input Roy Hodgson has in recruitment and I would suggest that it is less than it should be which is why some purchases / loans never even make it to the bench

11 games seems too quick to me tbh, that's basically end of November. Players are not given enough of a chance and are written off too easily. Some will naturally fit in easily, and hence quicker, but some will not.
Even Ronaldo have a difficult 1st season at Real.
