Time is a healer. Arsene Wenger has forgiven Jose Mourinho for calling him a "voyeur" but there is a guarantee that the Special One's run of results against the Frenchman rankle worse than any words spoken against him.
Wenger has been forced to watch on impotently as Chelsea assembled squads of ready-made talent - sometimes at the expense of his own beloved enterprise.
The Chelsea way, flying in the face of Financial Fair Play, is anathema to what Wenger and Arsenal represents - namely fiscal responsibility and nurturing talent from underage levels to the first team. But such things do not decide soccer matches or titles and, in that respect, the Chelsea way has trumped Wenger's prudent, long-term sustainability.
