Januzaj feels he is learning from the best in Giggs, whom, he is convinced, still has much to offer despite hitting his 40th birthday.
"Ryan is a legend, totally unbelievable," said Januzaj.
"If I don't know what to do on the pitch, I just go to Ryan and ask him what I need to improve on.
"He helps me a lot - and he can still carry on for a bit yet.
"He is 40 but I think he could play for another five years."
