Manchester United boss Sir Alex Ferguson says Arsene Wenger's signing of Thierry Henry was an Arsenal masterstroke.

Ferguson feels the arrival of the New York Red Bulls ace has lifted everyone at the Gunners.

Fergie said: "The fans' reaction was almost as if there's a new messiah arrived. There are no negatives as far as Wenger is concerned.

"OK, he has only got him for six or seven weeks but that six or seven weeks could be the most important for Arsenal's whole season."
