Arsenal boss Arsene Wenger is unsure he'd rate Alexis Sanchez his very best signing.

Gunners legend Thierry Henry feels Alexis can eventually take the mantle.

"It's difficult to compare Laurent Koscielny, for example, with Sanchez," said Wenger. "All the signings we made this year were good. Sanchez is one of the better ones, but you have to consider the price you pay as well to decide that because we paid good money for him.

"But whichever way you look at it, he is good value for money. He is one of the fastest to adapt to the Premier League. I believe it's because he feels accepted by the other players, that he feels he is an important player."
