(Reuters) - Arsenal manager Arsene Wenger refused to blame forward Alexis Sanchez's performance for the goalless draw at relegation-threatened West Ham United on Wednesday, saying the entire team must improve after a lacklustre display.

The Chilean has been one of Arsenal's most potent weapons in recent seasons but has scored just four Premier League goals this campaign, the latest in last month's win over Huddersfield Town.
