Ole Gunnar Solskjaer applauded Fred for building a career for himself at Manchester United after a rocky start, with the midfielder preparing to make his 100th appearance for the club.
Fred joined United in 2018 for a reported £52million from Shakhtar Donetsk, the deal seen as a significant coup for the Red Devils after he had been heavily linked with bitter rivals Manchester City.
Pep Guardiola was said to have seen Fred as the ideal long-term replacement for Fernandinho, but United fans were left underwhelmed by what they saw in his first season at Old Trafford, making just 17 Premier League appearances.
But he showed signs of improvement last season and has become one of Solskjaer's go-to players for the biggest matches, highlighting the manager's trust.
In 2019-20, Fred improved virtually across the board statistically, averaging more passes (66.4 to 69.5), interceptions (1.4 to 1.6) and touches (85.3 to 91.1) per game than he had in his first season.
He has dropped off in some of those areas this term, but his increase in tackle attempts (3.2 from 2.5) and interceptions (at 1.9 this season) per game, coupled with the fact he is losing possession less often (11.5 occasions, down from 14.5 per 90 minutes) suggests he has become more comfortable with his defensive role and the speed of the English game.
His 3.2 tackles attempted per 90 minutes is the seventh-most of all Premier League players to have featured at least 10 times this term, and Solskjaer has no doubt where the praise should lie.
"He's really done well. I've enjoyed working with him these past couple of seasons," Solskjaer told reporters ahead of Sunday's trip to West Brom.
"When I came in, he was a boy who was struggling a little bit. I got numerous questions about Fred in press conferences early on. As I said then, players coming into a new country, it takes time to settle - and it took some time for Fred to settle.
"He has settled now, he's grown in confidence. There's less time in the Premier League than what he was used to. He's quickened up his game, he's not getting caught on the ball.
"I'm not going to take any credit for that, of course. It's the coaches - I think Michael Carrick and Kieran [McKenna], they've been brilliant with him, but it's Fred himself who has had the hunger and humility to learn and want to improve, stick at it and keep working.
"There are not a lot of people who can say they've played 100 games for Manchester United. Hopefully there will be many more [games] to come - and hopefully he will score from outside the box soon, but I'm not sure it’s going to be with his right [foot]! I've tried to tell him."
With Solskjaer confirming Paul Pogba remains sidelined with a thigh injury, Fred looks likely to play again this weekend and his most-likely partner behind Bruno Fernandes will be another United midfielder who has attracted praise this season.
Scott McTominay scored the extra-time winner as United beat West Ham 1-0 on Tuesday to book their place in the FA Cup quarter-finals, taking the Scotland international's tally for the season to seven goals.
Only Bruno Fernandes (18) and Marcus Rashford (16) have more than McTominay across all competitions in 2020-21, with Anthony Martial and Edinson Cavani also on seven each, and Solskjaer is urging the midfielder to reach double figures.
"Of course, to add goals from midfield is vital," Solskjaer continued. "Last season our three forwards were brilliant and really efficient and scored goals - 60 odd - and Bruno came in and scored goals.
"We need more goals from midfield and Scott does have that ability to go box-to-box. He's a threat inside the box and he used to be a striker.
"I think for us to move up the league and be successful in the cups, we need our forwards to keep on firing - getting more goals - and I wouldn't mind some midfielders adding a few.
"If Scott can get into double figures then that would be a very good season for a so-called defensive midfielder."
