Van Persie knows it's the beginning of a new era under manager David Moyes.
"It is going to be a new era and a new challenge, with a new manager, maybe some new players coming," he told MUTV. "[Wilfried] Zaha is coming in from Crystal Palace, maybe some more. Maybe some will leave, nobody knows.
"But it is going to be a new challenge and everybody knows what our standards are: we want to win the league again and then hopefully add one or two trophies to that."
