Wenger rocked as rampant Reds punish Sanchez risk

Liverpool forward Philippe Coutinho shoots with his left foot but Arsenal goalkeeper Petr Cech was equal to it

Arsene Wenger's decision to leave Alexis Sanchez on the bench backfired as first half goals from Roberto Firmino and Sadio Mane set Liverpool on course for a vital 3-1 win over Arsenal on Saturday.

Wenger eventually brought on the Chilean international at half-time at Anfield and he set up Danny Welbeck for a goal that breathed life into Arsenal.
