Griezmann will fly to Brazil on Monday with the France squad having scored his first international goal in the 1-1 draw with Paraguay last Sunday. Arsenal, Liverpool and United have been monitoring the progress of the 23-year-old, with a view to stepping up their interest this summer. The winger enjoyed the most productive campaign of his career last season netting 20 times, helping Sociedad clinch a Europa League spot. Griezmann, who is rated at £25m, has not hidden his desire to move one of Europe's elite clubs and, according to reports in Spain, Sociedad are willing to sanction a quick sale with PSG frontrunners to clinch his signature.
