Van Nistelrooy warns Man Utd: Pellegrini can be Man City success
Van Nistelrooy told The Sun: "Pellegrini is one of the best coaches I worked under. He's a big strategist but nothing like Mancini.
"He's always in conversation with his squad, offering plenty of chances to young players.
"That characterises his quality work and he'll be good value in the Premier League."
