Best way to implement Football Livescores web app C#

I am developing a Livescores web app with asp.net c#. Server constantly (every second) retrieves big json from API. An array of live Matches that each contains the following: 1) MatchData (light data) 2) Stats (a bit heavier) 3) Events (a bit heavier) 4) Commentaries (a lot of text)

What is best way to implement that kind of behavior so the end user will get every-second updated data on a web page? (Sql server, cache, etc)
