The pair were outstanding for victory over Everton last Saturday.
On the new star duo, Wenger said: “Once the game has started, these guys have top-level experience.
“They know what's important and that's to focus on their performance.
“These guys are top quality players. Why should they not repeat the performance [vs. Everton]."
The boss added: “He has a very professional attitude in training and matches.
“I'm not surprised by that - to me, it's completely normal."
