Valencia 2-1 Celta Vigo: report
Valencia relied on the finest of margins at the Mestalla to edge out Celta Vigo and remain Barca's closest challengers in LaLiga.
Simone Zaza ended a six-week goal drought as he flicked home Parejo's corner at the near post to hand Valencia a half-time lead.
Celta, who became the first visiting side this year to take points from Barca's Camp Nou last weekend, were on course for another excellent point when Iago Aspas stabbed home from close range early in the second half.
However, the visitors were furious when Pablo Hernandez was adjudged to have tripped Nacho Gil inside the area and Parejo was given the chance to drive the resultant penalty past Sergio Alvarez despite the Celta 'keeper's best efforts.

Valencia look to get their LaLiga title challenge back on track against Celta Vigo at the weekend as they welcome the galicians to the Mestalla on Saturday night.
Just a week ago, Celta Vigo were dirupting Barcelona's title march and now the look to throw spanner in the spokes of Valencia's fine start to the season.
Getafe served a very harsh lesson to Valencia as they kicked and spocked their way to victory last Sunday night. It was Valencia's first loss of the year as they look to rebound against Celta Vigo.
They will be missing their crown jewel in Gonzalo Guedes, the man who causes so many problems for opposing teams with his speed and precision on the counter. He is out
Meanwhile, Ezequiel Garay remains out for the encounter while Carlos Soler suffered a slight injury during the Getafe game but trained well all week and should be good to go on Saturday night.
Under Carlos Unzué, Celta Vigo have blown hot and cold this season. Last weekend, however, they brought their A game back to Unzué's former workplace as they dismantled Barcelona on the counter.
They may not have had as many chances as the home side on that occasion but they scored as many goals and they will need to be as clinical against Valencia on the counter in this one.
Valencia pride themselves on how organised their defense is and with Marcelino in charge, they like to work on the counter once they take the lead meaning Celta will want to keep it at 0-0, or better, for as long as they can.
Sergi Gomez, who just returned from a calf injury, is out after suffering a collarbone injury against Barcelona while Jozabed is out due to suspension.
