Pep Guardiola said it can be an advantage for a player to return to manage an old club after Ole Gunnar Solskjaer was named Manchester United's caretaker boss.
The former Red Devils forward has taken charge as interim boss until the end of the season following the departure of Jose Mourinho this week.
Ole Gunnar Solskjaer wants Manchester United to "play without fear" but warned his players that they must embrace a team-first mentality. These are quality players and it's easy to get them to express themselves.
I've seen the last few games.
"Like me, he is an ex-football player for a big club and he has got the break that he needed". As much as you don't like your manager you've still got your own personal pride and you're playing for the football club.
At United he will be the favourite in most matches, similar to his spells at Molde and in contrast to his time at Cardiff when they were battling relegation from the Premier League.
Tottenham manager Mauricio Pochettino has been linked with the Old Trafford role
The former United striker takes over from Jose Mourinho, who spoke only of his pride at managing the club in his first public statement since leaving Old Trafford.
"[Ferguson] had a saying and I will never forget it: "If you're good enough, you're old enough", Solskjaer said.
"I've had 300-400 games as a first-team manager".
Mourinho was sacked after no progress with results or style despite spending almost £400m on 11 players in two and a half seasons in charge, while many of United's performances this season have lacked fluency. "Rojo you owe me £20k" according to the Sun.
"From day one, not only in the coaching staff but with the players, there's a lot of rumours that happen in football". I am one of them.
A man with a reputation for having hard third seasons throughout his career could not change that pattern at Old Trafford, with recent months being marked by high-profile clashes with star players Paul Pogba and Anthony Martial, and apparent discontent over the club's failure to sign a defender in the summer.
Former United greats David Beckham and Gary Neville have given their backing to Solskjaer on social media, as has his former Norway team-mate John Arne Riise and even his country's prime minister Erna Solberg, who appeared to accidentally leak the news of his appointment on Tuesday evening. "If he comes out and starts performing, then it will look like a good move".
