This is according to the Mirror, who understand Cech wanted assurances from Wenger before agreeing to join the north London outfit.
Cech has been granted his wish to join Arsenal - although Jose Mourinho is loathed to see the 33-year-old join a direct Premier League rival - and a deal could be completed within the next couple of days.
Cech’s arrival is likely to result in the exit of Colombian goalkeeper David Ospina, who is reluctant to drop down the pecking order at the Emirates Stadium.
The 26-year-old could complete a £4 million move to Turkish side Fenerbahce, with Wojciech Szczesny staying with the Gunners as back-up to Cech.
Major coup for Arsenal
Securing the services of Cech, who remains one of the Premier League’s best goalkeepers, is a major coup for Wenger.
While Ospina and Szczesny have always performed relatively well for the Gunners, neither is in the same class as Cech, who has been one of the world’s best for over a decade.
Cech was keen to stay in London, with his family settled in the English capital, and will continue competing for major trophies over at the Emirates Stadium.
Furthermore, a move to Arsenal will also allow Cech to break the record for most number of clean sheets in Premier League history. The Czech Republic international is currently four behind the retired David James, on 166.
Rob Green to replace Petr Cech
Over at Stamford Bridge, Mourinho has already begun the hunt for a replacement.
It’s understood that Queens Park Rangers goalkeeper Rob Green is Mourinho’s surprise pick; the England international, 35, will play second-fiddle to Thibaut Courtois.
Mourinho often expressed his happiness at having two of the world’s best goalkeepers in his ranks last season, but any injury to the brilliant Courtois next term would leave Chelsea vulnerable.
Green possesses plenty of experience but has never been a world-class goalkeeper and is prone to making the odd error, as England fans will remember from the 2010 World Cup finals in South Africa.
