The Lions won their first tour in 16 years at the weekend after edging out Australia 2-1 in their latest series, following a 41-16 win in Sydney.
Despite the win, Guscott believes that the Lions need to be granted more time in order to prepare prior to the tour.
"The Lions need more respect and understanding from the administrators running the domestic and European competitions," Guscott told BBC Sport. "Yes these are fantastic competitions, but the Lions, for a couple of months every four years, generates immeasurable excitement for players and supporters.
"Future tours need the support of these administrators to give the Lions the deserved preparation time required.
"The Lions is the biggest global brand in rugby, it has its place in modern rugby and must remain. Just ask the players and supporters their opinion."
Guscott picked up eight caps for the Lions during his playing career.
