Furious Barcelona boss Ronald Koeman has accused Paris Saint-Germain of trying to unsettle Lionel Messi ahead of their Champions League last-16 tie later this month. Koeman was irked by the latest comments coming from PSG where Angel Di Maria, a team-mate of Messi s on the international stage with Argentina, suggested his compatriot could head to the French side this summer once his Nou Camp contract expires. Yes, yes, I hope so, Di Maria said when asked whether Messi could join him in Paris. There are many possibilities. We have to be calm and things will develop. Those words were put to Koeman after Barcelona s win over Granada on Wednesday night and the Dutchman made no effort to hide his disdain.
