Ronald Koeman has accused Barcelona of living in the past as the Dutch coach took aim at his former club.
Koeman was dismissed in October and was replaced by club legend Xavi in the dugout.
And Koeman, who is set to take over the Netherlands national team for Louis van Gaal after the World Cup, says Barca is still living in the past and have not grown from a reliance on tiki-taka possession-based football.
He told Esport3:
I am in favor of dominating the game. If you play with three central defenders and five defenders, you cannot say that it is a defensive system.
With this system for three or four months we played the best games in recent years. The clearest example was the final against Athletic.
Barca lives in the past, from 4-3-3, from ‘tiki-taka’. Football has changed. Now it’s faster, more physical. You can’t live in the past.
