Arsene Wenger has dismissed suggestions that Arsenal already rely too heavily on summer acquisition Santi Cazorla, but says the Spaniard is nigh on unstoppable if the team is performing to its optimum.
Cazorla has featured prominently for Arsenal since his move from Malaga in the summer transfer window - quickly establishing himself as one of the most important players at the Emirates Stadium.
The 27-year-old endured a relatively quiet game in Arsenal's last encounter against Norwich, and the Gunners' defeat was attributed in part to Cazorla's lack of influence at Carrow Road.
Wenger, however, has rejected claims that Arsenal are only on song when Cazorla is in full flight, and says the Spain international was one of many players not at his best against Norwich.
"It is not as simple as just stopping Cazorla and stopping Arsenal," Wenger told a press gathering ahead of Arsenal's Champions League encounter with Schalke.
"Santi was a little flat at the weekend, and that was the same for many of the team, but I believe if the team play well then he is very difficult to stop playing."
Wenger would surely appreciate the opportunity to rest Cazorla for Wednesday's visit of Schalke, but a raft of injuries mean the former Villarreal midfielder will start against the Germans.
Cazorla has started every Premier League and Champions League game since arriving at Arsenal, while played twice for Spain during the international break.
