Boca Juniors playmaker Juan Roman Riquelme has reserved praise for Arsenal youngster Emmanuel Frimpong after the pair locked horns on Saturday.
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."
