Manchester United, Bayern Munich and AC Milan are all chasing Porto starlet Eliaquim Mangala, according to the player's representative.
The 22-year-old, who joined his current club in a £5.7m deal from Standard Liege back in 2011, has seen his reputation grow in Portugal.
Capped at Under-21 level for France, the defender has featured in all but three league games this term and taken part in all six of his side's Champions League group stage fixtures.
Porto have made a habit of unearthing gems in recent years - Radamel Falcao, Lisandro Lopez and Hulk all made their names at the Estadio do Dragao - and Mangala could be the latest star to move on to bigger and better things.
His agent Fabrizio Ferrari told Antena 1: "Manchester United aren't the only club interested in his services.
"Bayern Munich, Milan and other clubs want a great player like Mangala. He is doing a great job at Porto and shown he was a great investment for Porto."
