Barcelona have a golden opportunity on Monday as the Catalans can reclaim top spot in the La Liga table for the first time in two months when they take on Rayo Vallecano at the Montjuïc Olympic Stadium.
Real Madrid and Atlético Madrid did Barça a massive favor by dropping points on Saturday, opening the door for the Blaugrana to control their own destiny and return to first place with 14 games to go in the title race.
Hansi Flick was asked in a press conference on Sunday if he was aware of the slip-ups by the Madrid teams and what statement his side needs to make against a dangerous Rayo side, and the German coach made it clear Barça need to show a title-winning mentality on Monday.
