Portuguese star Cristiano Ronaldo, Manchester United star, wanted to leave Old Trafford during the summer transfer window, but he failed to leave despite the tireless efforts of his agent Jorge Mendes.

Ronaldo is no longer essential or one of the main pillars in the ranks of the "Red Devils", as Dutch coach Tin Hag has involved him in only two matches in 7 Premier League matches this season.

Since that time, the Dutch coach has been keen to keep the five-time winner of the Ballon d'Or, but - apparently - Ten Hag is ready to agree to his departure, as Ronaldo is looking forward to his departure next January, according to the newspaper "Telegraph" ( Telgraph) British.

The Portugal captain, who is said to have maintained his professionalism during his ordeal, hopes that his strong expected performance at the World Cup in Qatar this winter will lure Champions League teams to sign him at the Mercato winter, shortly after the conclusion of the World Cup.

And if a suitable offer reaches the "Don", it is believed that the fans of "Old Trafford" will bid farewell to the owner of their legendary number "7" after less than 18 months in Manchester.

Ronaldo looked frustrated while sitting on the bench during the Red Devils' 6-3 defeat against arch-rivals City in the Manchester derby last Sunday, despite making all five substitutions available to him, and Ten Hag chose not to participate in Ronaldo "out of respect for his great career".

The disastrous defeat led to calls from former United stars Roy Keane and Rio Ferdinand for coach Ten Hag to include Ronaldo, their former teammate, who scored his only goal this season from a penalty kick against Sherif of Moldova in the European League.

Kane claims Ten Hag showed "disrespect" to Ronaldo, warning that the situation would soon turn "for the worse".

"I think he should have been allowed to leave before the summer transfer window closed, but the coach prevented that because he needed multiple options, but you can't hold on to Ronaldo and sit him on the bench, he is one of the greatest players of all time," Kane added.

He continued, "Ten Hag involved Anthony Martial and scored two goals, this is justified, but the bigger picture is that Ronaldo did not play, he participated in two main matches in the European League. I think that things will deteriorate and complicate as the weeks go by."

Meanwhile, Ferdinand agreed with Kane and criticized Ten Hag's decision to keep Ronaldo on the bench against Man City.

"You can't have the best scorer in the world, who scored 24 or 25 goals last season on the bench."

He concluded, "The most difficult thing in football is scoring goals, and this man does it as well, if not better, than any other player."
