Porto goalkeeper Iker Casillas is dreaming big, with the Spanish icon aiming to reach the Champions League final this season.

The Portuguese giants open their Group G campaign on the road at Dynamo Kiev on Wednesday, with Casillas in an optimistic mood.

Porto have placed no better than the quarter-final stage, including last season, since winning the Champions League in 2003-04 but Casillas is reaching for the stars in his first season at Estadio do Dragao.

"We always want to win and get as far as possible," said the 34-year-old, who won three Champions League titles with Real Madrid.

"Emerging from the group stage isn't the aim – I'd like to get to the final at San Siro.

"But there will be some very strong teams along the way."
