Manchester United boss David Moyes has a 'big shopping list' of players he wants to sign in the summer.
Porto centre-back Eliaquim Mangala is one of the main targets as Moyes looks to replace Nemanja Vidic, who is set to depart for Inter Milan.
But he's by no means the only big-money name on United's shortlist, with Southampton defender Luke Shaw, Juventus duo Arturo Vidal and Paul Pogba, midfielder William Carvalho and Germany pair Toni Kroos and Marco Reus all in Moyes's sights as well.
Chelsea are ready to sell Romelu Lukaku for £17m at the end of the season - but only to a club outside the Premier League.
Jose Mourinho is keen to raise funds for his own transfer activity - with Diego Costa and Edinson Cavani his two top targets if he can find a buyer for Lukaku.
Borussia Dortmund and Roma are thought to be interested in the Belgian international.
