Don't feed the trolls guys.
We try not to but they always come back to try pin a whole series on problems on a single player, and ignore both data and good observation.
Why not replace Busquets with Arthur?
Why is always Rakitic getting blamed for the failings of the entire midfield when Busquets has been even worse? Of course you won't dare to bring him up since he's a La Masia graduate that played in Pep's Barca with Iniesta and Xavi. Ever since those two left he's been nothing but a glorified tree being heralded for his "unseen genius" that only "real football fans" a.k.a Cruyffista hipsters can appreciate.
Yep I think the better question. Is Rakitic-Arthur-De Jong or Vidal-Arthur-De Jong or Arthur-De Jong-Busi the better combination? Personally of these I think both Rakitic & Vidal at least can be most most attack minded for the lot, so maybe they should split duties (let whoever starts work for 60-70 minutes than sub). Than you can bring in Busi for Arthur the last 30 if we have a lead.
Now like I said I'd rather Busi and Rakitic be sold while we can get a lot for each, but the sky isn't falling if we keep them and use them in rotations--within the match and between matches.
