Petit says sacking Wenger would be a big mistake

Former Arsenal midfielder Emmanuel Petit believes the current players have become disillusioned and lack mental strength, but insists parting company with manager Arsene Wenger would be the “biggest mistake” the club could make.

The Gunners are set to finish this season trophyless for the seventh straight campaign after crashing out of the FA Cup at Sunderland on Saturday — three days after losing 4-0 at AC Milan in the first leg of their Champions League last-16 tie.

Petit, who formed a formidable partnership with Patrick Vieira in the early stages of Wenger’s reign, is convinced his fellow Frenchman remains the right man to get the Gunners back on track.
