Barcelona coach Luis Enrique says they won't underestimate Champions League opponents Manchester City.
Barca host City defending a 2-1 first-leg lead.
Enrique remarked: "We're playing against one of the favourites to win this competition. We're only 50% through the round and you only have to look at their players to see how much potential they have.
"City don't look tired to me. I think they have every chance of turning this tie around and I'm sure they'll be clinging onto that hope.
"They are missing Clichy, but have a key player back in Touré. They'll play with two forwards and depending on their approach, we'll work out how we can cause them damage."
