Jose Mourinho does not hang around.
Within weeks of of his return to stamford Bridge, he had turned his sights on Manchester United, seeking to test the mettle of new manager David Moyes.
Then he went for Manchester City, telling Manuel Pellegrini that he would be under immediate pressure in his first season.
On Wednesday night, he patronised Aston Villa boss Paul Lambert, just six years his junior, by saying that he reminded him of himself in his younger years.
Now he has launched an assault on Tottenham Hotspur, hijacking their move for Willian and compromising their negotiations with Real Madrid over the sale of Gareth Bale.
At this rate, he will not be receiving many Christmas cards.
Not that popularity has ever fazed Mourinho (right). He has spoken warmly about the reception he received from the Chelsea supporters last weekend, basking in the admiration of stamford Bridge.
That seems to be the only popularity he cares about. As well he might. Christmas cards don't win you titles.
