Huntelaar is not a bad choice. His strike rate is phenomenon at the Dutch League however, adaptibility is the question.
Kezman was a highly rated striker at PSV with him almost always topping the scoring chart. However, a move to Chelsea proved to be a really bad one as the "Kezman and Robben" link-up play was not as effective as when they were at PSV.

So i suggest Fergie to stop getting a striker for we have Rooney, Smith, Saha, Rossi and solskjaer vying for 2 spots. Unless one leaves, otherwise i think Fergie should concentrate on getting Giggs' successor.

Cheers.
