Aston Villa are set to be playing Championship football next season.
Villa look set to drop into the second tier, as they are 12 points adrift of safety with just seven league games remaining.
And Wilkins feels that the Midlands club will need a change in transfer strategy if they are to be able to cope with the challenges of playing Championship football.
“When they do go down, the Championship is so tough,” Wilkins said. “They will have spells where they play 11 games in 30 days.
“They are going to need [to sign] British players who have a bit of a scrap for you. I don’t like this rotation business, but it will have to come into play next season.”
Villa’s squad currently has a cosmopolitan feel to it, as they generally targeted players from abroad last summer.
The Claret and Blues’ recruitment has been widely criticised, with many of the new arrivals last year proving to be failures.
Villa signed a number of players from Ligue 1 in 2015, but they have failed to have the desired impact during their first seasons in English football.
Villa are likely to suffer a mass exodus in the coming months, with large volumes of their senior squad set to move on, as they prepare for life outside the Premier League for the first time.
