In fact the Spanish National Football Team literally took this game as a friendly as this starting line-up shows:
Spain pulled out some hurt pride & managed to lift their game in the 2ºhalf creating chances via XAVI - God only knows why he came on late in the 2ºhalf - PEDRO & FERNANDO LLORENTE scored a great goal in the 84th min for consoidation proposes. However, Argentina scored their fourth in the 91st min via SERGIO AGUERO from a header to let everyone know that this win was earned & won rightly because Argentina simply played better.
In conlusion, Spain was rightly beaten by a side who wanted to win more than they did & - lets be fair to Spain - because luck was not on their side today. Lastly, lets face it , a loss of this type is good as it puts everyone in the Spanish Team back on Earth & remembers everyone that Football is all about 100% concentration & less about uploading photos in your Twitter accounts.
