Former Arsenal defender Martin Keown rates the improvement of Martin Odegaard as "astonishing".
The former Real Madrid is in his third season with the Gunners, his second as club captain.
Keown said on TNT: "It's astonishing how he's risen in the game.
"It was his third Champions League game (against PSV), his first goal in Champions League football.
"He was at Real Madrid for many, many years and not really doing it.
"He won three Champions Leagues while he was there. But look at how he's come back and he's really controlling games. "
