The future of Antoine Griezmann has again become the subject of frenzied speculation. The Atletico Madrid striker had appeared certain to join Manchester United earlier this summer, however in a show of loyalty he scrapped those plans to remain with his current club. But now Barcelona have emerged as suitors for his services. With Neymar destined to join Paris St Germain, the Catalan club are in desperate need of quality attacking reinforcements. Reports suggest they have identified Griezmann as a potential addition to a frontline that already includes Lionel Messi and Luiz Suarez.
