The 18-year-old Gunners midfielder is set to feature for England Under-21s in tonight's European Championship play-off first leg against Romania at Carrow Road.
Wilshere, who won his first full international cap at the start of the season, has also been included in the senior squad for the Euro 2012 qualifier with Montenegro at Wembley next Tuesday, although Under-21s coach Stuart Pearce could yet retain him for their trip to Botosani.
Chamakh, who arrived at Arsenal on a free transfer from Bordeaux during the summer, believes Wilshere - fresh from a productive loan at Bolton last season - is a real talent.
"I have been very impressed by Wilshere," Chamakh said to skysports.com. "Wilshere is a great player and I think he is only going to improve further.
"As well as being a great player he is adorable off the pitch."
