London: Arsenal manager Arsene Wenger was charged with improper conduct on Monday for criticising match officials during his team's draw with Portsmouth. The Football Association said the Frenchman was cited "in relation to his words and behavior" toward the officials at halftime of Sunday's game. Wenger was unhappy about the awarding of a free kick to Portsmouth, which led to Noe Pamarot's opening goal in first-half injury time. He complained to the fourth official as they headed down the stadium tunnel. Wenger was ejected from the touchline by referee Steve Bennett and watched the second half from the stands, a few feet from the Arsenal bench. The game ended 2-2. Wenger has till January 5 to respond, the FA said. Last week, Wenger was fined 10,000 pounds, censured and warned about his future conduct after an angry sideline confrontation with former West Ham manager Alan Pardew during his team's November 5 loss to the Hammers.
