Barcelona coach Ronald Koeman says there'll be no underestimating Champions League opponents Ferencvaros.

Defeat at Getafe on Saturday has Barcelona coming into the game off the back of yet another disappointment, and memories of their 8-2 demolition against Bayern Munich in last season's quarter-finals haven't yet faded.

"At Barcelona you have to play to win titles," Koeman said at his press conference on Monday. "Domestically and in Europe. But there are strong teams and you have to prove your credentials.

"After what has happened [at the club] we're not the favourites, but we can go far."

Ferencvaros are considered to be one of the weaker teams in the group, also consisting of Juventus and Dynamo Kiev, but Koeman isn't taking them lightly.

"We expect [to face] a complicated team," Koeman added. "There are no easy games now. We have to create chances.

"We analyse all of our opponents and we respect them all. We have to stop their quality. They are good at the back and have important players in attack."
