Manchester City striker Sergio Aguero says Liverpool are the one team in England which can "hurt" them.
City go to Liverpool on Sunday.
Aguero told France Football: "...these last four seasons, Liverpool have become a very strong team and are now fighting with us to win the Premier League.
"It's the only team in the league that can hurt us. They have been chasing a new league (title) for years.
"Last season, they didn't go all the way, so they are very motivated. This year, they are in front of us and will try to go to the end."
Addressing the weekend's trip, Aguero added: We know that this is a ground where it's very difficult to win, but we'll try to do it because it has been a long time since the club last won there.
"This will be a key match for the title."
