Manchester United striker Ole Gunnar Solskjaer says Wayne Rooney and Cristiano Ronaldo are the perfect role models for the club's new signings.
Rooney and Ronaldo have emerged as two of Europe's leading lights
The duo have developed from raw talents into top-class internationals at United, who signed promising duo Nani and Anderson this summer.
"There is no better place to learn your trade," Solskjaer told BBC Sport.
"They've been given a good opportunity but the club has great players to develop into very exciting talents."
Portuguese winger Nani, 20, and Brazil's 19-year-old midfielder Anderson have been joined by Argentine forward Carlos Tevez, 23, from West Ham, while more experienced midfielder Owen Hargreaves, 26, also arrived during the summer - from Bayern Munich.
Solskjaer has been at United since July 1996 and has seen plenty of players come and go at the club.
He added: "The ones we have signed are young players and are going to need time to settle in.
"But the way we have nurtured Wayne and Cristiano is an example.
"They came very young and as really talented players but the gaffer Sir Alex Ferguson has made them into top world players and that is what you get by being at Manchester United.
"You get the challenge every day in training. They have to have that desire to improve all the time and the way Wayne and Cristiano have developed has been a joy to watch."
Now it's down to the nitty-gritty of the Premiership and I think they're going to enjoy this season
Solskjaer on the new signings
United would prefer Nani to give up his somersault celebration but that did not stop the player doing so after his goal in the friendly at Glentoran on Wednesday.
He has looked dangerous in pre-season, while Anderson was in the Brazil squad that beat Argentina to win the Copa America.
Solskjaer says the pair, along with Hargreaves, have settled in quickly at Old Trafford.
"It's always going to take time but they have settled really well," he stated at the launch of the Premier League Creating Chances community-based project.
"In the dressing room they have been great," he added. "They are good lads to be around and a great laugh.
"Now it's down to the nitty-gritty of the Premiership and I think they are going to enjoy this season."
