Valencia beat Espanyol 2-0 on Sunday afternoon thanks to goals from Geoffrey Kondogbia and Santi Mina.
With Barcelona beating Leganes on Saturday 3-0, pressure was on Valencia to maintain their impressive run and make next weekend’s clash between the top two a eye-catching clash.
In truth, it wasn’t Los Che’s best performance of the season as their Catalan hosts had the best chances of the first half.
Gerard Moreno and Sergi Darder both came close, hitting the post with their respective efforts.
However, despite their domination, the home side fell behind when French midfielder Geoffrey Kondogbia scored a 25-yard cracker.
Santi Mina scored a late second as Valencia secured an eighth straight win, and moved to within four points of league leaders Barcelona.
One sour point for the visitors was the dismissal of Marcelino, who was sent to the stands and will now miss the game against Barca next weekend at the Mestalla.
Second-placed Valencia, who last won La Liga in 2004, host the leaders next Sunday (19:45 GMT).
Barca who played Leganes on Sunday secured another three points thanks to goals from Luis Suarez (2) and Paulinho, whilst Real Madrid and Atletico Madrid, who sit third and fourth, respectively – drew 0-0 at the Wanda Metropolitano.
