The Welsh club beat Bradford City 5-0 in the Wembley final on Sunday and the Spanish defender was chuffed to bits to be a part of something so special.
"When I arrived (from Terrassa in 2007) they told me in four seasons they wanted to be in the Premier League," he said.
"I did not believe it was possible, it seemed impossible, just like a dream.
"Here we are six seasons later and we are established in the Premier League, we have won this cup and are in Europe.
"It shows how well run the club is, we have great characters and we need to keep that to succeed."
