Jose Mourinho wishes Harry Maguire had been in a Manchester United shirt during his time in charge at Old Trafford.
Maguire was named man of the match on his United debut, as Ole Gunnar Solskjaer's side rode out a sometimes-tricky opening 45 minutes to run out 4-0 winners over Chelsea.
Mourinho watched his former clubs go to work in his new role as a Sky Sports pundit and was full of praise for England international Maguire, who he reportedly courted a year ago.
"I think he fully deserved [to be] man of the match, he was as solid as a rock," he said.
"The tactical knowledge, the personality, that sense of reading the game, being alert all the time and having the confidence to play.
"He was fantastic. I think he did [give United confidence]. A team can be very dangerous in attack, but if you feel that the defensive mistake is around the corner, it takes away the confidence and you do not play as well as you can.
"When you feel there is something that allows you to play you are much more confident to do it.
"Maguire was good, [Victor] Lindelof was good. As I always said, Lindelof can be a very good player. With Maguire, I think they can be a very good couple."
Asked whether Maguire was the player he had been looking for before his Old Trafford reign crumbled, Mourinho chuckled and replied: "He arrived one year later!"
Marcus Rashford also won his former manager's approval after a two-goal display.
The England international converted Paul Pogba's superb through-ball having already won and dispatched a first-half penalty.
Mourinho reflected on Rashford's haul of 10 goals from 2018-19 and what he must do to help fill the void left by Romelu Lukaku's departure to Inter.
"That [10 goals] is not enough, he has to score more goals. Especially without Lukaku on the team," Mourinho said.
"He will be on the pitch all the time and I believe he has the qualities to be better and better.
"He is not just a kid with potential but a kid with ambition. He wants to improve, he wants to work.
"I believe this season he has a big opportunity to be a better player and score more goals."
Mourinho added: "Against a team like Chelsea today he is very dangerous. Against teams with lower blocks, more physical, more pressure on the ball and less possibilities for transition, I feel it is more difficult."
