Right now, a player like him would give us so much balance. We desperately need someone in the midfield who runs for the ball and has the ability to receive it in a tight area, pass it on straight away or turn and drift inwards.
It's not Busi's role to do that at all, but when he's playing there's already 1/3 of our midfield who don't run for the ball. When Rakitic plays alongside him, then 2/3 of our midfield don't really run for the ball. Already at that point, it makes it an incredibly difficult task for the last man in the midfield to run for the ball, because he is the only one for the opposition pressure to focus on. Don't get me started on if Gomes plays as well. Paulinho does actually run for the ball, but he lacks the dexterity for it to be very helpful.
I suppose that's one of the reasons why Valverde prefers a 4 man midfield. He recognizes our inability to play it out from the back and wants to add more options in that regard. No matter what position we play tho, if both Busi (of course he is) and Rakitic are part of our long term plan for the midfield, they will need someone dynamic around them to give them some room to do their thing. Arthur is a brilliant bet for at role like that, IMO. Thiago would be a safer, albeit priceyer option.
