Is there an online engine like Google Scholar which allows me to sort the papers by citation count? I could not find a way of sorting the list of relevant publications on Google Scholar on the number of citations. It would help a lot as I prefer to start reading well-cited references before moving onto less cited and more recent ones.
I am not looking to use a reference manager as I look for papers in diverse fields, many of which I do not go into depth.
There are at least four freely available databases which have this function. In random order:

Lens: In Lens, instead of the default Sort by Relevance choose Scholarly Citations (highest)
Microsoft Academic: In Microsoft Academic, choose SORT BY MOST EST. CITATIONS
Dimensions: In Dimensions, choose Sort by: Citations
ScienceOpen: In ScienceOpen, select Sort by cited by count
