Guardiola goes back to Barcelona with the team now coached by Luis Enrique playing their best football since he left the club in 2012. 'It will be a very special game for me,' he said after the teams were drawn to face each other. 'It will also be special for Thiago [Alcantara] and for the rest of the coaching staff.
