Atletico Madrid star Antoine Griezmann is reportedly certain to join Barcelona in the summer following a private agreement between the two clubs. Sport's Albert Roge (h/t Stuart Ballard of the Express) tweeted: "It is closed, yes, although obviously neither of the two parties will confirm it. At Sport we have already been informed of the private agreement that exists between both, and Griezmann will be Barca's in the summer 100 per cent." As noted by Ballard, the Frenchman was linked with a move to Manchester United last summer before remaining at Atletico. The Red Devils have since recruited Alexis Sanchez and Romelu Lukaku, which makes another attacker less of a priority this summer, and it seems Barca will be the beneficiaries.
