Manchester United have confirmed that the club have reached an agreement with Ajax over a £55.3million deal for Lisandro Martinez.
The 24-year-old Argentina centre-back, who flew into the UK on Friday to complete the transfer, still needs to undergo a medical and obtain a visa.
However, United don't anticipate any problems and the deal is expected go through in the coming days.
United will pay an initial £46.8m plus £8.5m in add-ons, making Martinez the second most expensive defender in the club's history after Harry Maguire.
