Paulinho did it with a 3-0 lead though tbf.
I don't know what's wrong with Rakitic. He can easily make more of those forward passes, but decides not to. If that's not bad enough, he seem focused most of the time on playing it on the left side even if Semedo/Dembele were in a better position with space.
I didn't think he was as bad as people are saying he was though so agree with that, but unless he improves in those areas, his time at Barca will be over by the end of this season.
He often doesn't get informed or doesn't sense the amount of space he has around him, or where the opponents are in relation to him. To be able to receive under pressure and move forward with the ball very often, you need to know at all times where you are in space and how many touches you can make before an opponent is in touching distance. Then you can make the call if there is space to turn and pass/move up, or you need to tap it back/sideways (what basically is considered a safety pass). Rakitic, Paulinho (so far), Gomes, all are making safety passes in positions and in situation where they can claim available space and gain speed with he ball.
Players like Rakitic, sadly, make Juventus' job easier. He basically lets them get away with whatever mistakes they make in their pressing. And they do make mistakes, in the sense that they sometimes arrive late to block the receiver. But if the receiver doesn't make them pay, their mistakes get unpunished.
