Only time will tell whether this 2-1 Clasico defeat to Real Madrid will prove to be a final referendum on Ronald Koeman's right to continue his increasingly pale imitation of a Barcelona coach.
But if those in power at the Camp Nou, where Barca suffered their fourth straight defeat to Madrid for the first time since the Beatles were breaking through in the 1960s, decide to take this performance as an indicator of Koeman's credibility -- not his legacy -- as someone in the right frame of mind, making the right decisions and showing his players the correct way forward, you would understand if they believe there are better options.
