Manchester United forward Cristiano Ronaldo is reportedly concerned over the club’s lack of movement in the transfer market. United ended up 35 points behind champions City, who pipped Liverpool to the title by a point, as the Red Devils registered their lowest-ever Premier League points tally. Ronaldo is ‘worried’ about United’s current approach in the transfer window, according to a report from AS.com. The Portuguese superstar is also being linked to his former club Juventus. A Sport report suggests that Ronaldo’s manager Jorge Mendes has offered the footballer to the Italian giants. Ronaldo made 134 appearances for Juventus, scoring 101 goals and winning two league titles as well as two Coppa Italia. Along with Ronaldo, Pogba, who was bought by the Reds for a record £89 million ($112 million), could return to his former club Juventus, while French champions Paris Saint-Germain have also been mentioned as a possibility. United have already confirmed through a statement that Pogba will leave the club when his contract expires at the end of this month.
