Porto striker Hulk has called on fans to get behind the team ahead of their Europa League match against Manchester City.
The Portuguese side host the Premier League leaders on Thursday evening in the first leg of their knockout tie.
"The fact we play at home in front of our fans always plays an important role," said Hulk. "We need the support of our fans to win and we can do it with them on our side. But we are facing a great rival.
"We know the qualities of City — they are one of the best teams in the world.
"It will be a very difficult match. We have to be very focused."
Porto are currently second in the Primeira Liga.
