The MP for Crosby has seen one alternative proposal which has been drawn up by the ABetterCrosby group and he says all avenues should be explored before the final decision is made on August 18.
Bill said: "I have looked at the ABetterCrosby group's plans and they seem to me to be another viable option for the development of Crosby.
"Sefton's planning committee must investigate all the options before making its decision. They must consider all the plans and choose the best one for the town.
"If that means delaying its final decision then so be it."
The MP said it is in all parties' interests to get around a table to look at all the options for Crosby Village.
Bill said: "It would be useful for Sainsbury's, the local businesses and the community, including the ABetterCrosby group to get around a table and involve themselves in a dialogue.
"Sainsbury's is a business, and I understand that they want to carry through the plans which will give them the best options for developing their business.
"But it is also in their interests to explore all the options as there may be better alternative plans which will not only benefit them, but also benefit the local community and local traders.
"Delaying the decision while the committee and all the interested parties can investigate the options seems to me to be the best possible option.
"We are looking at the future of the heart of Crosby here. We need to make sure that that future is one that is in the interests of the community, the residents and local businesses."
A survey to gauge Crosby residents' views on the Sainsbury's proposals has been added to Bill Esterson MP's website. Survey results will be handed to Sefton Council's Planning Department before the committee is due to make its decision on August 18. To have your views known, go to www.billesterson.org.uk
