Portugal goalkeeper Diogo Costa is among the names FC Porto could look to sell in the summer due to growing financial difficulties at the club, 90min has learned.
Costa has been established as a summer transfer target for Premier League sides Manchester United, Chelsea and Tottenham Hotspur in recent months, though the 23-year-old recently signed a new contract which took his release clause to around £65m.
It had been expected that with mounting interest in Costa from a number of European giants, the Portuguese outfit could hold out for that clause to be triggered before selling - though trouble behind the scenes at Porto may now present an opportunity for interested parties to sign the player at a cheaper price.
