Scholes, 36, now on ÂUnitedâ€™s coaching staff after almost two Âdecades of winning everything under the clubâ€™s most successful manager, reckons thereâ€™s plenty more to be achieved as Ferguson gets set to mark the 25th Âanniversary of his arrival in Manchester.
Scholes told the Sunday Mirror: â€œSir Alex has seen off ÂLiverpool, ÂArsenal and Chelsea in his time at United.
â€œHaving City Âchallenging him now will only be a big motivation for him to carry on.
â€œHe will want to make sure that City never finish above us while heâ€™s still in charge at Old Trafford.
â€œHe might have beaten ÂLiverpoolâ€™s record with a 19th title, but thereâ€™s absolutely no sign of him stopping.
â€œWhen you see this new team heâ€™s built, playing the football they are, thereâ€™s no reason for him to think about retirement."
