Ronaldinho admits he won't select a winner between Champions League opponents Barcelona and PSG.

The Brazilian has both clubs in his heart and also didn't dare to give a prediction on the score for Tuesday evening's Champions League Round of 16 first-leg tie.

"I will never choose between both teams," he said to Goal.com.

"They are both in my heart and it's difficult for me because I want both to do well.

"Anything can happen during a game and they are two big teams with world class players.

"In football, nothing is impossible, and every year there are small teams that win big."
