Reports have claimed United and Tottenham are keeping tabs on Mangala as they look to bolster their defensive options next season.
Italian giants AC Milan are also thought to be admirers of Mangala as Porto brace themselves for moves for the centre-back.
The 22-year-old has impressed for Porto this season in the Champions League and he is regarded as one of the best young defensive talents in Europe.
Mangala insists he is happy at Porto, but admits he would be interested in a move to the Premier League.
"I have a contract here till June 2016, however all players want to play one day in the top league in Europe," Mangala told Sky Sports. "I am no different to that.
"To be linked with clubs of the stature of Tottenham or Manchester United is the best feeling.
"I want to finish the season strongly and see at the end of the season if the reports are true."
