Arsenal boss Arsene Wenger fielded midfielder Chuks Aneke at centre-back for their thumping win over the Indonesian Allstars.
The Gunners ranout 7-0 winners.
"I played Aneke there because he was the most suited to play centre back because of his size. We had a congestion in midfield, we had many midfielders and I wanted to give competition at the back," Wenger told arsenal.com.
