Dutch legend Johan Cruyff believes Saturday's 3-1 El Clasico win has proved Barcelona remain top dogs in Spain.
Pep Guardiola's catalan giants had fallen behind Real Madrid in the title race, but victory moved Barca back to the top of the table on the results rule used in Spanish football.
Whilst Jose Mourinho's side have a game in hand, the result is likely to have left a psychological scar on the special one's side in the capital, and Cruyff believes it could be a defining moment.
"Based on what we've seen, it is clear that Barcelona are still ahead of Madrid," Cruyff wrote in publication El Periodico de Catalunya.
"It was not a great match. Barcelona were only able to play their own game for about 25 minutes when they really dominated, while the best Madrid could do was keeping up with Barca before the break.
"Nothing has been decided yet and the encounter at Camp Nou [in the reverse fixture] won't be decisive either. It's not a league between just the two teams.
"It's all about making as few mistakes as possible throughout the season. You have to get the maximum score from the other games, and have to be 100 per cent all the time. That's very difficult."
The former Ajax sensation's comments are unsurprising, given his allegiance to Barcelona - a team he played for between 1973 and 1978, and then coached for almost a decade in the late 80s through to 1996.
His comments will ring true to Los Blancos though, who are still in the domestic driving seat with a game in hand during Barca's time away in Japan at the FIFA Club World Cup.
