Atletico Madrid midfielder Tiago has insisted that the Spanish champions are "not scared" of Barcelona ahead of their Copa del Rey quarter-final second leg.

Barca, who have won their last six games in all competitions, will enter Wednesday's match holding a 1-0 lead from the first leg.

However, Tiago is confident that the capital side will turn the tie around in front of their own supporters.

"We have to use the momentum gained from the weekend win against Rayo Vallecano and take that into Wednesday's game," he told reporters.

"Right now Barcelona are on fire and seem to get better with every game they play, but it's a great opportunity for us against some world class players.

"Lionel Messi and Neymar are really good and in great form. We can only stop them as a team but we are not scared of them."

Atletico have lost twice to Barca in two separate competitions this month.
