Barrios > Scott > Wharton. This is most simple way to go about it. When fully fit, this is the order of these 3 players. Barrios and Scott are generalists, while Wharton is more of a specialist ( dlp role ). Aldo i got no problem with Wharton, and i think in thinks he does best, he is amazing, i think he wouldnt be as balanced as Barrios/Scott in double pivot with Caicedo. Lot of OOP weaknesses there, and it wouldnt maximise Caicedo in a right way. Barrios is someone who practically strives in everything he does. Passing, tackling, link up, first touch, flair. Whatever you need him to be, he will be that. He is tiki taka type of player that makes others around him much better just by playing with them. Way he avoids pressure and how he does the counterpress is insane ( Diego Simeone effect ), and his engine is on another level. Biggest compliment you can give to a player is saying his only real weakness are his injury issues. Every time he plays, he is practically best player in this Atletico Madrid team. But he was out for some time before, so that is something to be careful about. Other than that, he is elite level midfielder. Last, but not least, Alex Scott. What Alex Scott has above Barrios is his durability and the fact that he is already used to Premier League. Aldo he isnt insane passer, he is so much better than Wharton OOP, and that would suit Caicedo more, allowing him more freedom to go forward aswell. What i love about Scott also is the fact that he reads the game really well. He will step out to get interceptions, he is brave w/o the ball, and has tons of flair to break out of press. He is very well rounded and can become absolutely special player ( definitely on his way ). To sum it up, if these 3 were fully fit, Barrios is the best player here, no question about that. And he suits Xabi ball the best. But if Barrios injuries persist, then Scott is the right call here. I'd like to add that this is strictly comparison between these 3 and how they suit us. There is other midfielder out there aswell in WZE, Sučić, Tchouameni, Camavinga, Kone , Froholdt etc etc. Midfield market atm is deffo broken in terms of prices, but profile wise, you can get anything you need out there in next 2 windows. We just gotta choose wisely
