Porto are hoping Atletico Madrid choose Manchester United over Chelsea when selling Radamel Falcao.
AS says Porto will be due a tidy windfall from the sale as Atletico still owe them €28 million from the original transfer 12 months ago.
But should Falcao join Chelsea, that would end Porto's hopes of raising much needed cash from the sale of Hulk to Stamford Bridge.
United are also interested in the Colombia international and Porto are keeping their fingers crossed that should Atletico sell, Falcao will end up at Old Trafford.
