LONDON (Reuters) - Arsene Wenger must start learning from his mistakes if Arsenal are to compete at the highest level of European football, Alisher Usmanov, the London club's second-largest shareholder, has said.

The Russian billionaire, who owns 30 percent of the Gunners, is frustrated by Arsenal's worst start to a Premier League season which has brought four wins from their first 12 matches.
