Boca Juniors playmaker Juan Roman Riquelme has reserved praise for Arsenal youngster Emmanuel Frimpong after the pair locked horns on Saturday.
• Wilshere eyes additions
Frimpong impressed with an energetic performance as he played the whole 90 minutes of Arsenal's 2-2 draw with Boca at the Emirates Cup.
And Argentine midfielder Riquelme was impressed with the 19-year-old, who has yet to make a competitive performance for the Gunners after missing the whole of last season with a serious knee injury.
"[Frimpong] was the most important player for Arsenal ... him and [Jack] Wilshere were our toughest opponents," Riquelme told Goal.com.
Meanwhile, Gunners boss Arsene Wenger has outlined his intention to push for a work permit for Japanese midfielder Ryo Miyaichi, who spent last season on loan at Feyenoord.
He said: "My plan is to get a work permit for him and to put him on the pitch for Arsenal football club."
