Willy Caballero played in the Community Sheild loss to Arsenal, but the England No. 1 returned for the Premier League win over Newcastle and is relishing the competition.
Joe Hart is determined to keep fellow goalkeeper Willy Caballero on the Manchester City bench.

Manuel Pellegrini made it clear Caballero would be in his plans after saying he has "two No.1 keepers" ahead of the FA Community Shield against Arsenal, which the Argentine shot-stopper started at Wembley.
However, England No. 1 Hart reclaimed his place in the starting XI as defending champion City opened the Premier League season with a 2-0 victory over Newcastle United on Sunday.
And while he is relishing the challenge with Caballero, Hart has no plans to relinquish his spot.
"It suits me. I'm a fighter, I've been a fighter all my life," the 27-year-old told reporters. "I'll continue to do that. I'll carry on trying to perform to my best and hopefully keeping clean sheets.
"I wouldn't say it's given me an extra edge because I've always had an edge. Caballero is a great signing.
"We were sorry to lose [Costel] Pantilimon to Sunderland and we wish him well but Willy has come in - we know he's a great keeper and what he's done at Malaga. He wants to play as much as I do," Hart continued. "But I've got the place at the moment and I'm going to do everything I can to keep it. You always want to look to improve - whether it's small margins or big margins."
