The Argentinian is suspended against Granada
It's impossible to replace Leo Messi, but somebody will have to play his role this Sunday against Granada.
The Argentinian has missed 6 matches this season and usually Luis Enrique has chosen Rafinha to play his role. The Brazilian has played in the right win 4 times, while Arda and Alcacer were the others to replace Messi.
Luis Enrique said this Saturday: "We play in a way or in another depending on the profile of the players". Rafinha started against Sporting Gijon and Celta and also in the two Copa del Rey matches against Hercules.
The only time that Luis Enrique changed the whole system when Messi wasn't there was in the Champions League match against Borussia Mönchengladbach. Suarez and Alcacer played upfront with Neymar behind them.
