Spain thrashed Italy 4-0 in the final of Euro 2012 in Kiev on Sunday to win their third major tournament in a row.

Vicente del Bosque led his side to an emphatic victory in Ukraine to become the first coach to win a World Cup, a European Championship and a Champions League title.

Spain have now won the last two European Championships and the last World Cup in South Africa.

So are they the best national side to play the game?

Spain 2008-12

BBC chief football writer Phil McNulty:

The debate began long before Spain's goalkeeper and captain Iker Casillas lifted the trophy at the end of the Euro 2012 final. In fact the debate began long before the end of the tournament in Poland and Ukraine.

Germany have had great sides through the ages and Argentina won World Cups in relatively quick succession in 1978 and 1986 - but has anyone ever had a tighter stranglehold on the world game than Spain?

They have now been untouchable in three major competitions and already few would back against them in South America when the World Cup goes to

They are the ultimate combination of silk and steel. They conceded one goal in Euro 2012 and have the Barcelona "carousel" of Xavi and Andres Iniesta augmented by Real Madrid's Xabi Alonso in midfield.

Del Bosque felt confident enough in this brilliant side to ignore the claims of a conventional striker such as Fernando Torres, although he made a devastating late contribution against Italy.

David Silva and Cesc Fabregas more than compensated - and it was all done without their great goalscorer David Villa and iconic defender Carles Puyol.

The greatest? It would have to be a very powerful argument against Spain.
