Be wary of referee, Wenger tells players
Arsenal have just emerged from one refereeing controversy, with Mark Halsey having overturned a penalty awarded against them at Fulham last Saturday.
Wenger does not want his players to be involved in another controversy against PSV Eindhoven at Highbury. After all, he was watching on television last week, when bank director Messina sent off David Healy, Robbie Savage and Michael Hughes in the tempestuous 2-2 draw at the Millennium Stadium.
