Silva thinks Porto will win their semi-final against Lazio
Boavista striker Elpidio Silva has branded Celtic a one-man team and predicted that his side will face city rivals Porto in the Uefa Cup final.
Silva says that Celtic rely too heavily on Henrik Larsson and Boavista believe that they have devised a system that will negate the danger from the Swedish forward in Thursday's semi-final first leg.
Porto Alegre-born Silva said: "Strikers from Brazil are the best anywhere in the world.
"The Swedish aren't even the best in Europe.
"Larsson is just an individual, Boavista are a team.
"On Thursday, it will be 1-1 and we will finish the job off in the second leg in Portugal.
"Celtic are favourites, but we are dangerous on the counter attack. I would love to score in Glasgow.
Larsson is a great striker, but he isn't God.
Boavista goalkeeper Ricardo
"However, the Uefa Cup final will be between Boavista and Porto. I am sure of that."
Boavista's Portugal goalkeeper, Ricardo, was similarly dismissive of Celtic ahead of the Parkhead clash on Thursday.
He also believes that former Rangers target Mario Jardel - now with Sporting Lisbon - is a better player than Larsson.
"Celtic depend excessively on Larsson," he told the Sunday Mail newspaper.
"The match will be determined by how well we handle him, but we have prepared a special system, so it should be okay."
Henrik Larsson is on form again after his jaw break
Boavista warmed up for the Uefa tie with a 1-1 draw away to Moreirense in which they had six players booked.
That left Boavista languishing in ninth spot in the table.
But Ricardo insisted: "Our defence is great and they will find it hard to get past me.
"Playing in Glasgow first gives us an advantage, but it's vital every player gives 120%.
"It's the most important match in our history.
"This year, we will arrive at the final. I'm sure of that.
"Larsson is a great striker, but he isn't God. Mario Jardel is what I call a major goalscorer."
