Cristiano Ronaldo should "do himself a favour" and "close the shop" in the face of his struggles this season.
That's the opinion of Antonio Cassano, who reckons the Manchester United forward is no longer playing at the same level he was when he was winning trophies every year and that it is perhaps time to call it quits.
Cassano, who played for Real Madrid for two years before Ronaldo joined the club in 2009, has previously slammed the 37-year-old, claiming he's not one of the top five players in football history. His latest comments about him were made on the back of Spain's 1-0 victory over Portugal in the Nations League on Tuesday.
