Valencia started the new year no better than they finished 2016 as they suffered a humiliating 4-1 home defeat to Celta Vigo on Tuesday.
The home side conceded three times in the first 19 minutes at Mestalla as they handed a huge first-leg advantage to Celta in the Copa del Rey last 16 in their first match since the departure of coach Cesare Prandelli.
Iago Aspas opened the scoring from the penalty spot after only three minutes before Javi Jimenez turned the ball into his own net to put Celta 2-0 up.
Daniel Wass blasted in a third to prompt fury from the home fans just hours after hundreds staged a protest in the city centre against owner Peter Lim.
