Eliaquim Mangala has arrived in Manchester to undergo a medical and finalise a £31.8 million move to Manchester City, Goal can reveal.
On Friday Goal reported that City had made a breakthrough in talks with Porto over a deal for the France international, having given him until Sunday to accept their offer.
And on Saturday Mangala arrived at The Bridgewater Hospital in Manchester's Moss Side to complete a medical as he prepares to put pen to paper on a long-term deal which will earn him £90,000-a-week.
The 23-year-old, who was part of the France squad at this summer's World Cup in Brazil, will go on a short holiday before joining up with the rest of the City squad for pre-season training.
The deal brings an end to a long pursuit for City, who came close to signing Mangala in January but were ultimately frustrated by Porto's unwillingness to negotiate on a valuation.
Manuel Pellegrini has been searching for an elite defender to partner Vincent Kompany for some time, with Martin Demichelis and Joleon Lescott criticised for their performances last season and Matija Nastasic struggling for fitness.
Mangala has established himself as one of the most coveted centre-backs in European football during three seasons at Porto, though he is yet to earn a regular place in France manager Didier Deschamps starting XI.
