Worst team ever to contest a World Cup final must be

101 landed

The Dutch team in 2010 kicked their way to the final and stank out the final, the Argentinian team in 2014 were underwhelming but carried by Messi to the final

don't think I said final enough

Germany '66.  Slow, ponderous, unimaginative.  If Greaves had played instead of the water-carrier Roger Hunt, England would have won 4-0 in 90 minutes.

Sweden

'58

Yes Sweden with that famous team of theirs where the players just roll off of the tongue.

Hang on a minute ...............

Germany was pretty bad in 2002.

Argentina 1990
