Cascarino was quizzed on the breakfast show over stories, covered by talkSPORT, which have suggested that Cech is close to completing a move to the Emirates Stadium.
“I think the big difference between the two clubs is tactically – If I look at both managers and how certain results happen over the course of a season – I think he will definitely help them, but I don’t think he’ll be the difference between Chelsea and Arsenal,” he told talkSPORT.
How are Wenger and Mourinho different?
Arsenal manager Arsene Wenger is a boss who arguably encourages his teams to take more risks.
He likes the Gunners to control possession in all games, but he sets his side up based predominantly around attack and trusts the individuals in the team to adjust if the original game plan quickly goes out of the window.
Mourinho is a much shrewder manager and someone who knows how to go about getting a specific result, which sometimes means negative football.
How will Cech help Arsenal?
Presuming he completes a move to the Gunners in the near future, Cech will help Arsenal in a number of ways with his experience and leadership at the back of the team obvious qualities the Gunners will benefit from.
He may not be as sharp or as agile as he once was, but he can organise a defence and close out danger he sees developing in front of him.
