He said: "Arsenal fans can be completely relaxed that Wenger has got this signing spot on - Da Silva is a great buy.
"Once he has settled in he will show he has all the talent and quality in the world to score a lot of goals - and be one of the best strikers in the world.
"He is just as good as Torres and we will see which player makes the bigger impact. They have got a big year ahead of them.
"Da Silva is a great player with big potential.
"He is quick and can hold the ball up well and he's got a great left foot - and that always makes things a little bit harder for his rivals."
