The Dutchman believes his former club can win Saturday's crunch game against their fierce rivals because of their better cohesion
Barcelona are more of a team than Real Madrid, which can give them an edge when the clubs face off in La Liga on Sunday, says Ronald de Boer.
The Dutchman, who won the league title with Barca in the 1998-99 season, believes his former team's sense of identity can help them to come out on top in the decisive battle.
Real Madrid are three points clear of Barcelona with a game in hand on their rivals, but Barcelona would go top with a victory thanks to the head-to-head record between the sides.
