Paris Saint-Germain are expecting to be punished in some way by UEFA when the results of their Financial Fair Play investigation emerge in the coming weeks.

Spain

With Atletico Madrid looking increasingly likely to lose Barcelona transfer target Antoine Griezmann this summer, the club are turning their attention to possible replacements, and could look to bring Sergio Aguero back to the club. The Argentine is competing with Gabriel Jesus for a starting spot at Premier League champions Manchester City and the striker, who turns 30 this summer, could favour a move to a club where he's the main man up front.
