I'm sorry but if the only thing being seen as a positive, besides being relatively average, is his shouting ability, then we have a problem and if that is used as a reason NOT to replace him, then we're in trouble.
That's because you'll see what you WANT to see. As evident by this whole conversation. You mention Davinson Sanchez, who has the best pass completion out of any of our defenders.
But Sanchez usually gets abuse for his attempted long passes that are misplaced, whilst Dier and Toby tend to get a pass for those, certainly more of a pass anyway. I think Sanchez's awkward technique makes it seem like he's not comfortable on the ball, a bit like Sakho or Rudiger, when he's more comfortable than people think.
Again though, having a competent defensive midfielder to take that ball from him instead of relying on our centre backs to break lines would be a good start and help our centre backs out a lot more.
I will base my valuation on what I watch.
I don't use Sissoko's pass completion stats to tell me he's a better passer than most. I mix that with how many passes he tends to make a game as well as the touches he makes and see that it's likely he's making simply 5 yard passes unlike say Ndombele or Lo Celso who will look to play more dangerous passes with a lower pass completion, yet making alot more.
You can't tell me you understand the game only to then tell me you rate Ben Davies enough that he shouldn't be upgraded.
No I don't use stuff just to base on what I want to see. I pointed out that
- passing stats might be misleading
- and overall I would not base any players evaluation soley on this year.
But I see that in this part I made bold, you actually think that Sanchez is better passer than Toby (and furthermore that he is best passer from our defenders), and this is where I certainly draw a line. We live in different worlds and I don't think they can be merged even in my wildest of imaginations.
