The Czech Republic international made a number of top quality saves to keep Stoke City at bay as the north London side played out a goalless draw at the Britannia Stadium on Sunday afternoon.
The draw left Arsenal top of the table on goal difference from second-placed Leicester City heading into next weekend’s crunch clash with Chelsea at The Emirates.
Cech joined Arsenal from local rivals Chelsea in the summer transfer window and has been a regular fixture in the north London side’s team this term.
And Souness believes that the goalkeeper’s arrival has helped to spread confidence throughout Arsene Wenger’s side.
Speaking on Sky Sports after Sunday’s draw at Stoke, Souness said: “If you look this year, Man City went to The Emirates and had most of the ball, but they turned City over. Bayern Munich went to The Emirates, had all the ball, and they turned them over.
“I think there’s a resilience about Arsenal this year that’s not been there for a number of years.
“I can’t tell you how important it is to have a really top-class goalkeeper, who gives you points that you don’t deserve. And that makes them [Arsenal] a real danger [in the title race].”
Arsenal are now gearing up for their showdown with Chelsea at Emirates Stadium as they look to return to winning ways after back-to-back draws.
