Many expect Wayne Rooney and van Persie to be Sir Alex's first choice attacking pairing this season, but Ritchie believes Welbeck and Hernandez will still get their fair share of action and can only thrive in van Persie's company.
"It's a great opportunity for Danny and Chicha to learn from one of the world's best," Ritchie told ManUtd.com. "They've got to embrace the fact they'll be playing alongside a fantastically, successful and decorated player whose at the top of his craft. When he's on song I think he's unplayable.
"I don't think either should be afraid. If Manchester United didn't think both had fantastic futures then they wouldn't be here. Neither have anything to worry about - they should both embrace van Persie's arrival and take as much as they can from a master."
