The retired former Stoke defender has claimed that the Gunners addition of the experienced goalkeeper could be telling.
The Gunners have been crying out for a top-class goalkeeper for a number of years, with no consistent option between the sticks for the North Londoners in recent campaigns.
With the Czech Republic international falling behind Thibaut Courtois in the pecking order at Chelsea, the Blues allowed the experienced stopper to move across London to the Emirates Stadium.
Cech has already helped Arsene Wenger’s men claim the Community Shield and will be an influential member of the Gunners’ side this season.
Higginbotham feels that his addition has the potential to help Arsenal close out games and could be the difference this season.
“[Cech is] Without any shadow of a doubt, the best signing of the summer so far and the leader who could wipe away the flaw which has been at the heart of Arsenal,” Higginbotham told The Independent.
“I’m talking about that lack of leadership which has contributed to them losing their discipline and falling to pieces in the late stages of games.
“In 11 of Arsenal’s 38 Premier League games last season they conceded in the last 15 minutes.
“They dropped eight points because of events after the 75-minute mark and that was because they would go chasing the game, both full-backs bombing up at the same time and the anchor of midfield also stepping up.
“No fewer than 12 of the 36 league goals they conceded last season were shipped in that final quarter of an hour.
“Cech is the man who can put a stop to that, the one who will demand that the players directly in front of him don’t lose it. He will be their eyes and ears.”
Arsenal fans will have high hopes for this season, with some scintillating football in the second half of last term showing that they have what it takes to compete for the Premier League title.
Cech is the only major addition at the Emirates Stadium so far this summer, with Wenger hoping that he will have the majority of his players fit and available for the bulk of the campaign this time round.
