Arsenal boss Arsene Wenger has reportedly laid into his players following their disappointing performance against AC Milan in the Champions League on Wednesday.
The Frenchman is believed to have called an emergency meeting at the club's training ground yesterday after they returned from their 4-0 thrashing at the San Siro.
It is believed that his angry outburst, which included a demand for huge improvement, left a number of the players shocked, according to The Mirror.
The Gunners will be under pressure to perform when they take on Premier League opponents Sunderland in the FA Cup fifth round on Saturday.
