Manager Arsene Wenger hailed Theo Walcott after his 15-minute cameo helped to rescue Arsenal from Champions League misery against Hamburg.
The 17-year-old substitute inspired a late improvement in Arsenal's performance which produced two goals in the last seven minutes to secure a 3-1 victory.
Wenger said: "We will give Theo more games now - because there are so many of them coming up. When he came on he provided power and pace - especially when he switched from the left to the right. And it helped us master Hamburg physically."
