Is Rakitic to be Blamed for Barcelona's Champions League Debacles?

Ivan Rakitic's Presence in the midfield of Barcelona, when it got overrun raises questions about the Croatians ability to control the game.

Ivan Rakitic is in the middle of the storm at Barcelona following the spectacular, but a humiliating loss at Anfield. To an extent, the fans are justified to raise fingers at the Croatian. He was literally 'Missing in Action' on the pitch of Anfield.

With him and Coutinho literally going invisible, Barcelona was reduced to a two-man midfield when the initial needs were for four men. Is there more to the presence of Rakitic in midfield and all those spectacular collapses in midfield?
