I don't think either that Rakitic is good anymore, but we are exagerrating here.
Remember when Rafinha started to play for us?
He was all over the place all the time, our midfield was all over the place and our team played some 5-0-5 formation wherever he was on field.
Or take Samper, in the past very hyped young player. When he played, we often looked strange, he looked strange and badly positioned, who couldn't get any balls in defensive part of a game and his passes are sometimes extremely-wtf-level-of-strange with those strange Pirloesque long balls, totally wrong fit (balls) for our style.
So, a current Raki, no matter how bad he is, he is still way better than Rafinfa from his early years at Barca and from ANY Samper, for example.
My point, Paulinho, even Gomes and other players would probably be better than a current Rakitic.
But saying that any Barca B midfielder who has to learn 100s of things in movement, positioning, defending, decisions, experience would be better a current Raki is just not true.
Again, I am not defending him, just saying that he is not THAT bad
