Manchester United boss Sir Alex Ferguson is delighted with the impact made by Robin van Persie.

Eyebrows were raised at the £22million paid for a player of that age. But the return has been instant.

Ferguson believes his goals tally can only improve the more his players get used to him.

The Scot said: "Hopefully that understanding gets better.

"I think there is more awareness about the runs he's making, the awareness he has up front."
