No fluidity, no press, no speed, terrible first touch, gets tired after 20 minutes. I love the bloke but this isn’t a team that will constantly whip balls in and even when we can he’s dropped deep anyway. Hurts to say it.1852195I’m sorry, but Ronaldo completely kills our attack.

In a mediocre season for the club, the five-time Ballon d'Or winner was the standout player as he scored 24 goals in 38 games across competitions. He managed to score 18 times in the league, 13 times more than any of his teammates.However, he is yet to open his tally for the current season. It will be interesting to see what's next for Cristiano Ronaldo in a United shirt.Manchester United star Cristiano Ronaldo played his first ever Europa League game against Real SociedadManchester United's Cristiano RonaldoCristiano Ronaldo has won it all in his career. He is a five-time UEFA Champions League winner and is the record goalscorer (140) in the tournament and is popularly called 'Mr. UCL'.However, Manchester United's recent clash against Real Sociedad marked the Portugal international's first ever appearance in the UEFA Europa League.His debut in the competition didn't go as he would have liked. However, the reason the Portuguese is playing in Europe's second-division tournament is because of the inconsistent campaign the Red Devils had last term.They could only manage to finish sixth in the Premier League during the 2021-22 season. Ralf Rangnick was appointed as the interim manager after the club parted ways with Ole Gunnar Solskjaer.Rangnick also left the club after the conclusion of the season and Ten Hag has been brought in since to get the Red Devils back on-track.The Dutch manager was able to get his team back to winning ways after a calamitous start to their campaign. The Red Devils won four games on the trot after losing their first two games of the new season. United are currently fifth in the Premier League table.However, the prevalent issues in the team are still quite significant. Hence, despite promising recent form, Ten Hag will have his hands full for the rest of the season to have a successful campaign.
