The agent of Porto defender Eliaquim Mangala has revealed the interest of Manchester United and AC Milan.

Mangala is finding his best form for Porto this season and Fabrizio Ferrari says he is attracting attention from Europe's biggest clubs.

"The Rossoneri, Manchester United and Bayern Munich are on his trail. But the boy now thinks only of Porto, we'll talk again in June when the market reopens.

"He was an important investment for Porto, but he will be well worth it."
