Valencia were not finished as they regained the lead through Paco Alcacer just before the hour mark and that proved to be decisive as they picked up a famous three points.
Read how it all unfolded in Sports Mole's minute-by-minute live commentary of the action below.

Alba is sent from the field after picking up a second yellow for a late challenge on Barragan.
Time is running out for the home side and in truth, they are creating very little. That said, you just get the feeling that chances will arrive in the latter stages. Barcelona look to their bench for the second time as Tello replaces Fabregas. Make no mistake about it, Valencia are worth their lead here.
