Arsenal hero Martin Keown is convinced by the quality of Reiss Nelson.

Nelson, 17, has made seven appearances for Arsenal in all competitions this season. The youngster came off the bench in Arsenal's 1-0 Europa League loss to Cologne last night and almost drew the sides level late on.

“Famous victory for Cologne, let them take their night," Keown said.

“They haven't had too many good ones.

“But I think Nelson can be something special, little flashes there of brilliance. That was a great run, pity he didn't score."
