Leicester City will have to spend £20million if they want to sign Luan Vieira from Premio.
However, there is also reported interest in 23-year-old Brazilian Luan but The Sun suggests he will not come cheap, with a fee of £20m being mooted.
Luan's agent Jair Peixoto has revealed that there is a strong chance his client will be making the move from Porto Alegre to the Premier League provided the English champions make an acceptable bid.
"There is no talk of priority. We will close with the first to arrive with what we demand," he said.
"Luan could be registered as a 'special player' too, he fits it, and therefore he would not have any obstacle in case of an agreement.
"It was a conversation to show what we want as a business model, our ideas and what we plan to achieve.
"We didn't set a deadline for the bid to be made. It could be tomorrow or in 10 days."
