The comparative needs something to be compared with;
therefore "I am bigger than X!" and of course the conjunction than.
No sooner said than done (almost simultaneously do the cause and effect occur).
"Sooner you than me."
(In written formal English, "Sooner you than I").
Never confuse than with that.
Francophones this is your umpteenth warning (parce-que than se traduit en tant que que en franšais)!
