Even if you play badly in some matches, you need to play smart. Valencia did that today and managed to do the things needed to win in time. Even though they can't play a very superior game, they can still manage to score goals.
That's what amazed me about today Valencia's game, they didn't have good statistics, instead of attacking they preferred to defend & looking for gaps to make counter attacks.
Honestly, I don't think their current position is an achievement even though they are in a better place than before. It is Ruben Baraja's job to maintain their performance this season. In the next match, Valencia will face Las Palmas, they're not a weak team at the moment and Valencia must show their consistency.
