tonali isn't your textbook regista though. he's a pretty good passer, but he's more of a box to box player.
btw pjanic is the least of our problems. we'd need a proper 6 though. we have a couple of them, neither are good enough atm.
i'd obviously keep pjanic as he's our best and most reliable midfielder, matuidi has an other year in his legs/lungs, bentancur has (unfulfilled) potential and would be a bad deal to sell, but the others are a mess. ~4 months into the season and neither of can, ramsey and rabiot can be trusted for whatever reason. 3 freebies on a total of ~19m net, great job.
