Their target is Bayer Leverkusen goalkeeper Bernd Leno.
The Sun says the Gunners are lining up a £25m summer move for the 26-year-old.
Arsenal’s new head of recruitment Sven Mislintat has a wealth of Bundesliga knowledge from his time at Borussia Dortmund.
And he has reportedly convinced Arsene Wenger that Leno is the best option as Cech’s replacement.
The German stopper already surpassed 220 Bundesliga appearances, missing just four league games in his first six full seasons.
Leno stopped five out of eight Bundesliga spot-kicks back in 2013/14, including an amazing four in a row.
