Manchester United interim manager Ralf Rangnick said Cristiano Ronaldo's hattrick against Tottenham Hotspur on Saturday was the best he has seen from the Portugal star at Old Trafford. The No 7 helped his side defeat Antonio Conte and company 3-2. Ronaldo hit his landmark 806th goal, which makes him the highest goal-scorer in the history of football. He has scored for Sporting, Manchester United, Real Madrid, Juventus and the Portugal national team. While the 37-year-old now has 59 career hat tricks, only one other before Saturday had been in a United jersey — in January 2008 against Newcastle during his first six-season spell at the club.

We were just joking and maybe it makes sense to send him to Portugal for three days, then have him not training for two days, then have him back training on Thursday, if that's the way he performs. Maybe we'll have to do that for the rest of the season, the German said after the game. The opening goal in the 12th minute was certainly impressive with Fred flicking the ball for Ronaldo, who sent a swerving shot into the top left corner from long-range.
