The duo are out of contract this summer and, while one-year extensions are possible, they are approaching the twilight of their respective careers.
Both United stars will be 34 when next season kicks off. In contrast, Luke Shaw will be 24 and Diogo Dalot just 20.
Shaw is now United’s undisputed first-choice left-back. When he is fit and firing, the same should be said of Dalot on the opposite flank.
If the Portuguese youngster excels as expected, that will leave Valencia and Young competing for scraps.
They would not be bad options to have from the bench or when games are coming thick and fast. But will it be enough for the experienced pair?
Young in particular continues to impress. And, while he is versatile enough to come in for Dalot on the right or Shaw on the left, he could be faced with a challenge for regular starts.
Valencia is less impressive these days. It could be argued that he does not deserve another year at United. But, if the pair sign, it may be with the understanding that they are phased out over the next 18 months.
It is time the United new guard get their chance. Shaw is proving what he can do and Dalot will surely follow.
