If his move from Juventus is confirmed, Ronaldo would likely go into Fantasy listed as a forward.
He would also attract major interest over the international break after Gameweek 3.
Indeed, many managers will consider activating the Wildcard chip to fit him into their squad.
Impact on Fernandes
Ronaldo enjoyed a prolific three-year spell for Juventus, scoring 81 goals and supplying 16 assists in Serie A.
Significantly, 23 of those strikes were penalties.
Bruno Fernandes (£12.1m) is currently Man Utd’s first-choice penalty-taker. Nine of his 18 goals came from the spot last season.
Man Utd have been awarded a minimum of 11 penalties in the last three seasons, with their total of 37 being more than any other side.
But Fernandes’ potential as a big-hitter will be significantly affected if Ronaldo joins and takes over penalty duties, instead lifting Mohamed Salah’s (£12.6m) position as the go-to midfielder.
A Ronaldo return could also disappoint Mason Greenwood’s (£7.6m) 12.8 per cent ownership.
Greenwood has played up front and scored in both of the first two Gameweeks. But he would likely be rotated more often to accommodate for Ronaldo.
Change in formation?
Managers have mainly spent big in midfield at the start of the season, with Fernandes and Salah the two most-popular players in Fantasy, owned by 57 and 53 per cent respectively.
Having a premium forward now looks a wise tactic, given all three are strong captaincy options for managers.
Indeed, that change in squad structure could start as soon as Gameweek 4, when Man Utd host Newcastle United.
If Ronaldo’s return is confirmed and he takes penalties off Fernandes, it could be a turning point in Fantasy this season.
