I am assuming your question is on the cricket world cup...
there are a lot of countries which did not win the world cup...
out of them, the strong teams are...
South Africa
Newzealand
England
these are the three strong teams which did not win the world cup...
rather than these three, there are a lot of countries like
Bangladesh
Afghanistan
Zimbabwe
Ireland
Scotland
Nepal
Kenya
Namibia
etc...
