A number of Newcastle's French signings were also on Wenger's radar.
Wenger said: "Newcastle have made good buys and done very well on the market. You go for quality players, you do not look very much where they come from.
"I spoke about the core of English players that it is easier to keep them together, than if you have players from Spain or South America. The most important is the quality of players, and on that front Newcastle have done very well."
