That is the opinion of Luke Chadwick, a former United player, who believes Ronaldo has improved on the pitch since Ten Hag was named the club's new permanent manager.
United's season has been another disaster, with Ole Gunnar Solskjaer's stint coming to an end and interim manager Ralf Rangnick not faring any better.
Despite United's troubles, Ronaldo has kept his half of the bargain by delivering in front of goal since his return to Old Trafford in the summer.
With 24, the five-time Ballon d'Or winner is by far the club's leading scorer this season, more than doubling his previous total.
However, Ronaldo's play has improved significantly in the matches since Ten Hag's impending arrival was reported on April 21, scoring in each of the three games since then. The additional confidence, according to Chadwick, may be beneficial to the No.7.
"I think one moment that really characterized up Cristiano Ronaldo was when he lost the ball after attempting a short flip, but then sprinted back 50 yards to make the challenge."
