Darwin Nunez could be given his dream shirt number if he completes a transfer to Manchester United this summer, though it all depends on whether Erik ten Hag wants to keep Anthony Martial or not.
Though midfield remains the priority position to strengthen in the summer transfer window, United are also in need of more firepower due to their dwindling centre forward options. Marcus Rashford's dismal form in front of goal this past season hasn't helped his case to lead the line, Edinson Cavani is leaving the club when his contract expires and Mason Greenwood is unavailable.
As a result, Cristiano Ronaldo is the only realistic senior striker option Ten Hag has at his disposal at present. Although he did finish the season as the club's top scorer with an impressive 24 goals, he is 37 and can't be relied upon to lead a line for an entire campaign. That's even if he does decide to stay at Old Trafford considering the lack of Champions League football in the forthcoming season.
