Yaya Toure has insisted that Manchester United are still a dangerous team ahead of Tuesday's Manchester derby.
United have struggled in David Moyes's first season at the club, slipping to seventh in the Premier League.
However, they overcame a 2-0 first-leg deficit to beat Olympiacos 3-2 on aggregate in the Champions League, and Toure feels that they do pose a threat.
"We have to be careful because derbies are never the same and they will certainly have a lot of desire to try to beat us," Toure told The Mirror.
"I always feel United are a good team and if they play like they did against Olympiacos last week, we have to be careful."
City are currently third in the table, six points behind leaders Chelsea.
