Cédric admitted his frustration after his late goal for Portugal was not enough to give them victory over Mexico in their opening Confederations Cup clash.
The Saints defender struck in the closing stages to put Fernando Santos’s team 2-1 ahead, only for Hector Moreno to level the scores in added time.
Cédric felt the result was a harsh one on Portugal, who will face tournament hosts Russia on Wednesday.
"We were the more dangerous team,” he said. "We knew Mexico like to have the ball, that they have quality and that they are a strong team with good players, but we were superior and we created more opportunities.
"We left with a sense of frustration after this game. But this is the first game and the result is not a bad one.”
Ricardo Quaresma had put Portugal in front, in Kazan, only for Javier Hernández to equalise shortly before half-time, ahead of a dramatic conclusion to the game.
Portugal and Mexico share second place in Group A, with Russia topping the standings after their 2-0 win over New Zealand.
