Barcelona coach Luis Enrique says they won't underestimate Champions League opponents Manchester City.

Barca beat City 4-1 on aggregate last season to reach the quarter-finals of the competition but head coach Luis Enrique expects a level tie this time around.

"City aspires to the (Champions League) title just as we do," Luis Enrique told his club's official website. "They are a hard rival, one of the hardest that we could have asked for.

"It's going to be a very complicated tie, of that I'm certain."
