Arsene Wenger believes Andrey Arshavin has what it takes to become an Arsenal star, after the Russian's match-winning turn against Blackburn.
After watching his side contest a 120-minute epic with Roma in midweek, there were worries that the Gunners may be vulnerable to an upset when they returned to Barclays Premier League duty on Saturday.
But Arshavin is cup-tied in Europe because of his earlier exploits with Zenit St Petersburg and was recalled to the starting line-up.
For Wenger, his performance was vindication of a vigorous training regime the player has undergone.
"He has worked hard. I think he's quite surprised how hard he's worked," said the Frenchman.
