The 36-year-old completed his first session yesterday, since he signed a two-year contract with the Red Devils.
Ronaldo had a face-to-face chat with manager Ole Gunnar Solskjaer in his office, before getting into his training gear to ramp up his preparations for this weekend.
The Portugal captain was spotted driving into Carrington in his £170,000 Lamborghini Urus, one of a number of supercars the car-loving superstar has in his possession.
According to the Sun, Ronaldo ensured that any property he moved into had ample space for his fleet of luxury cars, with a total value of £17million.
Despite costing almost £200k, Ronaldo’s Lamborghini is merely a runaround compared to his other cars, with a Ferrari Monza valued at £1.4m, a £2.15m Bugatti Chiron and a £1.7m Bugatti Veyron Grand Sport.
Ronaldo was also gifted a £516k Brabus G-Wagon by his girlfriend Georgina Rodriguez last year, with the Portuguese superstar posting an image of the car on his social media.
