First of all, Cristiano Ronaldo's experience of leaving Manchester United was very unpleasant. His suspected diving performance against England in the World Cup led to Rooney being sent off. It has become the target of criticism from British fans. After winning the treble for Manchester United, he chose to leave Manchester United and join Real Madrid. At that time, he also created the highest price in the world.

After joining Real Madrid, his performance is very stable, and he can score more than two goals and assists every season, which is the absolute core of Real Madrid.

Although Juventus did not perform well in the Champions League, it still has absolute dominance in Italy. Moreover, his age has been gradually increasing. It is a very good choice for him to get an annual salary of more than 30 million at Juventus and play healthy games.

Moreover, the situation of Manchester United is not good now, and the competition in the Premier League is very fierce now. Liverpool and Manchester City can be regarded as a duel. Arsenal, Tottenham, Everton and leicester city are all strong.

Manchester United coach Ole Gunnar Solskjaer is a famous player, but his command ability on the spot is not strong. Manchester United may not even get tickets to Europe this season.

At the same time, Manchester United's strength is also relatively average. There are many contradictions within the team, and the contradiction between Bogba and the team has gradually become public. Mashal and La Herford also occupy a very important position in the team. Therefore, if Ronaldo returns to Manchester United, he will not adapt to the atmosphere here.

Moreover, the current Premier League pays special attention to physical confrontation, and the pace of attack and defense conversion is very fast. This requires a lot of physical fitness for the players. So I personally don't think Cristiano Ronaldo will return to Manchester United.

However, Ronaldo may return to Manchester United as a head coach or staff member after retiring.
