Teenage striker Santi Mina scored four goals as Celta Vigo ran riot against Rayo Vallecano, hammering the Madrid side 6-1 at Balaidos.
The Spain Under-21 international had not scored a single league goal this season before Saturday night's game, but everything he struck against Paco Jemez's side turned to goals.
Former Rayo striker Joaquin Larrivey cancelled out Manucho's first-minute opener after just six minutes, and then Mina put Celta in charge midway through the first half.
Mina and Larrivey added to their tallies before the break as Rayo collapsed, and the teenager scored twice more in the second period to cap Celta's biggest win of the season, taking them one point above Rayo in the Primera Division table.
Rayo produced an admirable display against Real Madrid in midweek despite losing 2-0 and would never have imagined they were in for such a thrashing when Manucho headed in Adrian Embarba's cross to open the scoring with just 23 seconds gone.
Embarba put in a dangerous cross again just moments later for Amaya to head at goal, but this time Celta goalkeeper Sergio Alvarez was able to save.
Celta needed just six minutes to get themselves level, with Nolito toying with Amaya on the byline before squaring the ball back to Larrivey to knock in, although the Argentinian opted against celebrating the goal against his former employers.
More chances for either side followed but Celta took the lead in the 20th minute thanks to another sublime piece of skill by Nolito, who drew four players towards him before picking out Mina in the area and the striker made no mistake from 10 yards out.
Seeing that his experiment of a three-man defence was not going to plan, Rayo boss Jemez made a double substitution on 27 minutes bringing on full-backs Nacho and Tito for Abdoulaye Ba and Lica.
However, his changes did not have the desired effect as his side conceded twice in the space of three minutes.
Larrivey tapped in Celta's third goal on 37 minutes after Tono failed to hold Nolito's shot, and then Mina ran on to Michael Krohn-Delhi's through ball to chip Tono to make it 4-1 with still 50 minutes of the game remaining.
The half-time break brought little respite for Rayo, who were picking the ball out of the net again on 50 minutes as Mina turned in Fabian Orellana's cross.
The youngster then grabbed his fourth goal as Nolito's pass sliced open Rayo's paper-thin defence, allowing Mina to round Tono and pass the ball into the empty net.
There was still plenty of time for Celta to dig the knife further into their opponents and they could have equalled Real Madrid's tally of nine goals against Granada last week, with Nolito striking the woodwork and Tono making smart saves to deny Larrivey and Orellana.
