Not so sure that's the case anymore. Shit passers don't own the midfield at the World Cup for their national teams. There could be other issues with him that are impacting his performances, i.e. tactics, being overplayed and others.
He didn't look like a player who can't pass out there.
Maybe we kind of limit our midfielders by how slow we're passing to the point that every single attack looks like long, boring positionals with no penetration. Using this in a defensive way so as to keep the ball longer away from our defense could have something to do with it.
Thing is we often slow the game down, and based on what I've seen in these games, it's not because Rakitic can't pass.
