Manchester United are ready to move for Porto's highly-rated defender Eliaquim Mangala in the January transfer window, according to the Guardian.
The Red Devils have identified the 22-year-old as the perfect long-term replacement for either Nemanja Vidic or Rio Ferdinand - but will face stiff competitions from several clubs, including Chelsea and Manchester City, for his signature.
Mangala, a France international who holds a Belgian passport, began his professional career with Standard Liege in 2008. He stayed there until 2011, when Porto signed him for a €6.5m fee.
However, the Portuguese giants could recoup over seven times that amount if a club opts to trigger his €45m buyout clause.
With the likes of Monaco and Paris Saint-Germain also keen on Mangala, it's perfectly plausible that Porto will receive that sum of cash.
But Premier League champions will monitor Mangala closely between now and Christmas, with scouts poised to submit detailed reports on the 6ft 2in centre-back.
