"We're an exciting team to watch and we're learning to manage games better than we have done in the past".
"I don't want to make it smaller than it is, but on the other side I don't want to make it bigger than it is", he told a news conference.
Although Casillas will now be fully focused on helping Porto secure their first Primeira Liga title since the 2012-13 season (they are five points clear of Benfica after 25 games), his time in Portugal is coming to a close.
