Are FC Porto’s transfer dealings possibly the best in the world?

Late on Tuesday night, news broke out from Iberia announcing that Real Madrid had signed 23-year-old Brazilian right-back Danilo from Porto for €31.5 million.

Danilo, who was signed for €13m from Santos back in 2011, has scored three goals in 23 games for Porto in the Portuguese top flight this season.

Looking at the deal from Porto’s end, the transfer once again showed the club’s amazing ability to sell players at maximum values in order to keep their finances ticking along.

For over a decade Porto have showed an incredible talent for either selling home ground talents for top whack, or alternatively they attract rising stars from South America, introduce them to European football, and then they sell them on for a profit.

In total, since 2004, FC Porto have made €601 million in player sales.

The two top deals in the club’s history have been the €45 million sales of Radamel Falcao and James Rodrigues to Atletico Madrid and AS Monaco respectively.

Porto have also sold five players for €30 million or more, including Ricardo Carvalho to Chelsea, Anderson to Manchester United and Eliaquim Mangala to Man City.

Porto are currently second in the Portuguese top flight, three points behind leaders Benfica.
