Porto centre-back Eliaquim Mangala appears to be closing in on a move to Manchester City after he was pictured at Manchester airport having reportedly undergone a medical.
Mangala, 23, who is expected to cost City 40 million euros, has been a long-term target for the club. They first bid for him at the end of the January transfer window, although a move could not be agreed upon then.
There were reports that the France international was spotted on Saturday at Manchester's Bridgewater Hospital, where City often take prospective signings for medicals.
Mangala and Roma's Mehdi Benatia were the two defenders at the top of City's shortlist this summer.
They allowed one central defender, Joleon Lescott, to leave when his contract expired, and only have three specialists in the position -- captain Vincent Kompany, Martin Demichelis and Matija Nastasic.
Mangala, who was an unused member of France's World Cup squad, has also been linked with Chelsea and Manchester United.
City have already made one signing from Porto this summer, bringing in midfielder Fernando for 15 million euros.
