There’s a rough old whiff emanating from Stamford Bridge these days, and the source of the stench is Roman Abramovich, the Chelsea owner. Roberto di Matteo, the manager he sacked last week, was the eighth dismissed since he bought the club in 2003. That’s quite a turn-over, even for an oligarch who likes to get his own way, but getting rid of di Matteo is significant because the Italian delivered the prize most coveted by Abramovich, the European Cup. Not even José Mourinho could get that into the Chelsea trophy cabinet. When it comes to football, the world is not enough for Roman Abramovich. In fairness to the unshaven money machine, I know people who have worked for him, and they have nothing but admiration for his kindness, charm and generosity. Seriously.
