Giggs says Scholes' return from retirement is massive for the club.
"So much â€“ the experience heâ€™s got, the qualities heâ€™s when these young players are either injured, arenâ€™t playing, or have lost form. Thatâ€™s when, really, you need to help them," Giggs told manutd.com.
"When theyâ€™re flying, you just let them get on with it, but if you see them losing confidence or maybe looking a bit down if they think theyâ€™ve not played well, thatâ€™s when you help them. Thatâ€™s when your experience comes in because weâ€™ve all been there. When I was younger I looked up to the likes of Bryan Robson and Steve Bruce, who helped me a lot."
