The shocking recent setbacks suffered by Barcelona and Real Madrid, domestically and in Europe, aren't caused by problems that will be instantly solved by the sackings of Ronald Koeman or Carlo Ancelotti.
Barcelona, of the two, are more undermined by their coach.
They remain a high-tone squad, capable of competing for trophies this season, and Koeman's insistence on playing formations and brands of football that don't suit his personnel isn't helping. Were Xavi, or a less heralded candidate like Paulo Sousa, parachuted in to take over this week, there's every chance that a clearer, firmer perspective on how to play 4-3-3 football properly might make a perceptible difference quickly.
