Barcelona superstar Lionel Messi is impressed by the team building at Manchester City.
Messi feels City are building a team that will strike fear into opponents at home and abroad.
"They have the vast financial power to compete and therefore they will become a real threat if they are managed properly," he told the Sunday Mirror.
"It takes time to make your mark but every season you see them improving. And they will continue to improve when they are signing players like Aguero."
