Winger James Rodriguez, Brazilian defender Alex Sandro and Eliaquim Mangala, who is also a target for Manchester City, are all on Fergies' shopping list says Italian paper Tutto Mercato.
With Patrice Evra being linked to several club's in Europe, Sandro could be the ideal man to replace him.
As well as City, Tottenham have shown that they have an interest in City young defender Mangala who was signed by Porto for €6.5 million.
All three are players that Porto would much rather keep hold of, but the lure of the Premier League could prove to be too tempting.
