Speaking to BBC's Final Score, he added: "I think that this was a great performance.
"It’s difficult, three minutes from the end we were 2-1 down and one minute we scored two goals. We wanted this title and we deserved to win this title.
"This is for all our supporters, for all our supporterss in Abu Dhabi, for the chairman, for the owner.
