After fell from the Premier League in 2018, Swansea won the championship matches in 2020 and 2021.
Since then, they had finishes from 15, 10 and 14 in the second layer.
Shehan believes that the upcoming administrative appointment of Swansei should be part of the reconstruction process if the club is re -establishing itself as competitors for promotion.
“Get it correctly, this is all I would like to say,” added the former Luton and Southampton coach.
“Let's do it at the present time, yet it seems, whatever, the club should start building to be successful, and start laying the foundations for its place and where it should be, because there are few good levels in the tournament.
“It is important to reach a place where you are a team of the 10 best teams, then a team of challenges, because after that, you have teams like last year and this year they are likely to be in their own bond.
“This is where we need to go and as long as we are on the same page, everything is good.”
