Arsene Wenger believes the injury that could sideline striker Lucas Perez for eight weeks was caused by a 'deliberate kick'.
Arsenal manager Wenger accused Reading defender Danzell Gravenberch of making a 'stupid' challenge on Perez in Tuesday's 2-0 EFL Cup victory for the Gunners at the Emirates Stadium.
Perez will now miss a chunk of Arsenal's campaign with an ankle problem, leaving Wenger nonplussed that Dutch defender Gravenberch avoided punishment for the challenge.
Wenger likened Gravenberch's tackle to the challenge that led to a red card for Granit Xhaka in Arsenal's 3-2 win over Swansea on October 15.
