Manchester United had on Friday announced that they had reached an agreemet with Juventus to re-sign Cristiano Ronaldo from Juventus for a fee around €15m (£12.87m) plus a further €8m (£6.86m) in add-ons.
It was understood that personal terms have been agreed on a two-year contract, with the required aspects of the deal to be finalised before the deadline on Tuesday night.
National Daily further gathered that the Portugal captain had successfully undergone a medical in Lisbon over the weekend.
The 36-year-old Portugal captain who scored 118 goals in 292 games during his first spell with United between 2003 and 2009 was on Friday confirmed to be quitting Juventus by boss boss Massimiliano Allegri, who revealed he was told by the player he had “no intention” of representing the club again.
Meanwhile, United Solskjaer boss had warned his Manchester United forwards that Ronaldo would likely be going straight into the first team.
The Norwegian added: “He is not signing to sit on the bench. He is going to make us a better team.
“We need to get all the paperwork done, hopefully we can get that sorted and we can announce it 100 per cent.
“Then he is away with Portugal, they have three games, his last game is Tuesday (September 7) and then we can get him back to Manchester and involved as soon as possible.”
