John Murtough said Lisandro Martinez will bring quality and experience to Manchester United as the Argentine was finally confirmed as United's third summer signing.
United announced the arrival of Martinez for an initial fee of £46.8million, rising to £55.3m, earlier this month, but the deal was officially confirmed on Wednesday afternoon. Martinez has joined United on a five-year contract, with the option of an additional year.
Martinez, 24, is a left-footed centre-back and he made 36 appearances under Ten Hag at Ajax last term. Martinez took part in his first training session at Carrington yesterday and he is likely to make his debut against Atletico Madrid in Oslo on July 30.
