Petr Cech's influence at Arsenal cannot be understated. The Czech goalkeeper has been an inspiration since joining the Gunners from Chelsea over the summer.
Following an opening day blip in the 2-0 home defeat to West Ham, Cech, who moved from Stamford Bridge for £10 million, has kept six Premier League clean sheets.
His form is a major reason as to why the Emirates club currently occupy second in the table and are level on points with leaders Manchester City.

Thanks to statistics released by the Telegraph, you can see just how important the former Chelsea favourite has been to his new club this season.
Cech tops the table when it comes to save percentage and currently saves an incredible 82.4 percent of the efforts he faces.
Stand-in Chelsea keeper Asmir Begovic, who is deputising for the injured Thibaut Courtois, does not even make the top ten.
Stoke City's Jack Butland is behind Cech with 80.7 percent while compatriot Alex McCarthy is in third on 80.6 percent.
David de Gea and Hugo Lloris make up the top five while Joe Hart, Tim Howard, Heurelho Gomes, Adrian and Boaz Myhill also feature in the ten.
Chelsea's decision to allow Cech to join their rivals could prove to be their biggest mistake of the transfer window.
Of course, they couldn't force the keeper to stay given his service to the club and desire to play first-team football.
Cech had also professed his desire to stay in London, but Chelsea could have played hardball and commanded a much bigger fee. After all, he was worth it.
