This won't come as news to anybody, but Robin van Persie is good at football.
If Manchester United fans were concerned about their team's ability to hit the ground running this season following the departure of Sir Alex Ferguson, the Dutchman's striking master class against Swansea must have come as the sweetest form of reassurance that things are going to be all right.
Van Persie scored twice in United's 4-1 win, and if his first goal was the result of his superb poaching instincts, the second featured skills that few players in the world could match.
Receiving the ball deep, van Persie attacked the goal like a shark honing in on a victim which it knows has no chance of surviving its naturally superior weaponry.
As Swansea defenders backed off in terror, the former Arsenal forward sliced inside and out before lashing a vicious shot into the top left corner of the net.
No side with van Persie in its starting 11 can be anything but a title contender.
