Ole Gunnar Solskjaer has leapt to the defence of Cristiano Ronaldo ahead of Saturday's Manchester derby.
The 36-year old has divided opinion since his return to Old Trafford - scoring crucial late goals in the Champions League against Atalanta and Villareal, but facing questions over his overall value to the team.
Ronaldo has registered only 27 attempted presses in the Premier League this season - one of the lowest figures for a regular outfield starter.
But ahead of the Portuguese superstar's first Manchester derby in 12-years, his manager told his weekly press conference that he has no regrets about signing Ronaldo.
"He's one of the best players that's ever walked on this planet," said Solskjaer. "And his impact so far on and off the pitch has been absolutely immense.
"The goals he scores, the way he conducts himself in and around the place. How people can see that as a negative... I can't see that one.
"We're really, really pleased he's started off as he has. He scores goals, works for his team, and is a top, top professional."
Saturday's game is United's first at Old Trafford since their 5-0 mauling at the hands of Liverpool a fortnight ago.
Since then, they completed an easy 3-0 win away to Tottenham - ending Nuno Espirito Santo's reign in the process - and salvaged a 2-2 draw away to Atalanta in the Champions League.
"We’ve moved on from that one," said Solskjaer of what he previously described as his "darkest day" at the club.
They held a team bonding day in Hale on Thursday, ahead of their City clash.
Solskjaer added, "Of course it’s going to be in the history books but we’ve had a good week. Good results away from home, difficult games, and the mindset is positive.
“Of course we’ve got to go into this game believing we can do good things. It’s a local derby and everyone knows what’s at stake.”
