No need to make it personal...
And in your attack on my ability "to separate" you are imbuing yourself with said ability as if you can divine that this player's performance this season was solely down to "bad coaching". This player's performance is EXACTLY that which he displayed in his almost 2 seasons at Juve - and I watched him there...did you?. The only outlier in his last 3 seasons is his purple patch in the 3 months after his xfer/loan to us...and even then there was nothing mindblowing about that performance.
Whatabout "a lot of players"? Well, I don't care about "a lot of players" because we aren't considering wasting money on them...we are already wasting money on them. I care about this player and he's not good enough.
Again, no need to make it personal...
And would you like to share with us his qualities that make him "an exceptional talent"? In my mind Messi is an exceptional talent and performs no matter what he's up against.
And not changing your mind is not a virtue...I'd like to have my mind changed everyday...gets me closer to truth and, as has been said, a foolish consistency is the hobgoblin of little minds.
Yeah, I'm going where the evidence leads me...'tis a fruitful place. Were Kulu to have shown any ability to get the best of other PL players this season, or stamp his presence on a game, or show some growth as a player then perhaps my opinion would have changed. But since he didn't and I like to allow the evidence to guide my opinion instead of forming it and disregarding intervening data my opinion hasn't been changed and is consistent with the data.
If you respond, please, enough with the ad hominem and just play the ball.
