Jose Mourinho has a rocky relationship with Barcelona - although, it was once very bright.

That came after Eto'o labelled the ex-Manchester United boss 'one of the best people' in football.
"I'm sick of saying that this guy is one of the best people in the world of football," he said. "I ended my career and the first person to send me a message was this man,
