Porto striker Falcao has agreed a new two-year deal with the club -seemingly ending any prospect of a move to Chelsea.
Falcao, who scored 38 goals last season as Porto won an eye-catching treble, was reportedly a target for new Blues boss Andre-Villas Boas, who himself made the switch from the Estadio do Dragao this summer.
A release clause of 30million euros had been in place - a figure that has now been raised to 45million euros, or nearly £40million.
The Colombian striker, who had also been linked with Atletico Madrid, is now contracted to the club until the end of the 2015 season.
Porto have told Liverpool and Tottenham they are prepared to listen to offers for their title winning stars - but only if their huge price tags are met.
Liverpool target Rolando has been valued at £17.5million while the strike partnership of Hulk and Falcao, who interest Tottenham, have been given valuations of £10m and £30m respectively.
Porto did not lose a single game on route to winning the Liga Sagres, Portugal's top division, this season and also look set for a place in the Europa League final after earning a 5-1 lead over Villarreal in the semi-final first leg.
Columbia international Falcao has scored 14 league goals this term while Brazilian Hulk has hit 22 and 25-year-old central defender Rolando helped his team concede just 13 goals over the campaign.
Porto president Pinto da Costa is preparing himself for a barrage of offers for his stars but he has set the bar for how hefty the bids should be.
He said: "The idea is to keep our players because they are all under contract. If any club is interested we would study their offers - if they are above the release clauses - but we are very quiet."
