Ole Gunnar Solskjaer expects Anderson and Nani to develop into world class talents at Manchester United.
"They've been given a good opportunity but the club has great players to develop into very exciting talents.
"The ones we have signed are young players and are going to need time to settle in.
"But the way we have nurtured Wayne [Rooney] and Cristiano [Ronaldo] is an example.
"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."
