Manchester United finally confirmed the signing of Lisandro Martinez, 10 days after the original announcement of their intentions to sign him after completing a medical. United had agreed a fee of £46.8million, rising to £55.3m, for Martinez on a five-year contract, plus an extra optional year earlier this month, but the deal had not been confirmed until Wednesday afternoon.
The deal had been subject to a medical, but an announcement was required as Ajax had to inform the Amsterdam stock exchange of material transactions.
Martinez, 24, has been in Manchester for almost two weeks, after flying in to complete a medical days after the original announcement.
