The City striker will step up his training schedule this week in a bid to be ready for Saturday’s visit of Liverpool after a six-week absence due to a hamstring injury.
Kun feels the Blues are a stronger outfit this season and has been impressed by the start of De Bruyne, who has scored six goals and made six assists in just 14 appearances.
“I’m really happy because I think the club did a great piece of business bringing Kevin in and you are always happy when a quality player arrives and he is certainly that,” said Aguero.
“The few chances I’ve had to play alongside him have been encouraging because we started to get an understanding of how each other plays.
“As I say, he is a great player and it’s really important he settles in and shows us what he can do and he’s also a great lad off the field as well so I’m looking forward to playing alongside him again.”
Aguero says the arrival of international team-mate Nicolas Otamendi has also strengthened the Blues defensively, with the former Valencia star adding a different dimension to an already impressive back line.
“Nico is a good player who will help our team – and the more Argentinians the better as far as I’m concerned!” he said.
“He had a great season with Valencia last season and that’s helped earn him a move here.
“We need a big squad because we’ve got lots of games and many competitions we’re trying to win and all the players we’ve brought in over the summer have made us stronger.”
