Wilshere was outstanding for England in victory over Brazil last week.
"I heard he played well," Sagna told Arsenal Player. "I texted him and he replied to me and was quite happy. It’s good for him and I’m happy because he totally deserves it.
"He can deal with pressure. The way he wants to play [is with] power. He doesn’t think too much about his future, how well he will do, and how people will think about him."
