The attacker has refused to dismiss the threat posed by his side's arch-rivals, despite their Clasico failures, before reflecting on his chances of representing Spain at Euro 2012
Barcelona forward Pedro has highlighted physicality as arguably Real Madrid's most dangerous trait.
The 24-year-old told AS on Monday that Jose Mourinho's men should not be underestimated, regardless of their continued struggles against his team, as a potential meeting in the Copa del Rey quarter-finals between the giants could be on the cards.
"Yes, it is possible to cross with Real Madrid, but let's go step-by-step," said Pedro. "They are very strong physically, they are a tough opponent."
Barca demolished Segunda Division B side L'Hospitalet 9-0 in the third round of the tournament, but despite his joy at the result, Pedro proceeded to call for focus on their upcoming last-16 tie with Osasuna.
"I'm happy about the last game, but you have to think about the next, which will also be complicated," continued the Spain international.
"We know that the road is long and difficult, but we can do it calmly."
Pedro also discussed his chances of success for Spain, with whom he won the World Cup with in 2010. Now he wants to taste further glory by earning a place in Vicente del Bosque's 23-man squad for next summer's European Championship.
"Hopefully I can go to the Euros," commented Pedro. "The group [Spain have been given] is quite complicated and it will surely be a tough tournament, but it is too early to know if I will go.
"Fingers crossed I can, though, because it could give me the special pleasure of winning that title - the only one that I'm missing."
