When I said that it was based on the best versions I have seen of those players. The best version I've seen of Bissouma and of Bentancur is currently better than the best version of Sarr I have watched. Of course form and fitness will come into the equation when actually picking the starting XI, but if I'm asked to pick our best XI when all fit and firing it's still Bentancur, Bissouma and Maddison for me as our midfield 3.
Why, you're sponsoring by any chance?
You seem to be ignoring the fact they play in a different role though. So lets say what you are saying is correct and that there is very little difference between Sarr and Bissouma as far as their level is concerned, then it comes down to what role Bentancur is better playing, and for me that's the all action 8 and not the holding 6.
Where/when have you seen Sarr play in that press resistant 6 role? Personally I haven't seen him do it so I have no idea if he can play that role well. Certainly not as well as I know Bissouma can play it because I've seen him do it a good number of times.
It’ll be quite exciting to see such quality competition for the places in the midfield three. I agree with your assessment, but Bentancur and Bissouma will need to maintain good form to keep their starting spot when you have Sarr ready to step in.
So how well will he screen the back four? How good is he in tight spaces on the half turn under pressure, How disciplined is he to hold his position and not burst forward etc etc. There's a whole lot more to Ange's 6 than breaking up play, and the 6 and 8 is a different role altogether. He's doing very well as the box to box 8, but he doesn't look much like a press resistant 6 to me from what I have seen and certainly not as good as Bissouma(which is what you said). If you want to play those 3 together Bentancur has to play the 6 which he is very capable of, but again isn't better at it than Bissouma is when Biss is on top form.
