Arsenal have ended months of speculation by finally announcing the arrival of Martín Zubimendi in a deal worth almost £60 million ($81.9 million).

Martin Zubimendi, the 26-year-old Spain international, has joined Arsenal from Real Sociedad on a five-year contract for a fee of around €65million (£55.8m; $76.6m). Arsenal will pay more than Zubimendi’s €60million release clause but the compromise means they will be able to pay the fee in installments, rather than as one lump sum.
