The Gaurs move atop the standings at the end of the fourth round of matches in the Indian Super League (ISL) with their third victory in four games.
Another hat-trick by Coro (47', 51', 54') after the one against Bengaluru FC last week and a double by Manuel Lanzarote (9', 18') sandwiched by Markos Sifneos (7') and Jackichand Singh's (30') strikes for the visitors was enough for FC Goa to overcome Kerala Blasters 5-2 at the Fatorda stadium.
Sergio Lobera named an unchanged 11 for the first time as Adrian Colunga continued to be out of action for the Goans.
Rene Meulensteen brought in Loken Meitei in place of CK Vineeth who was red-carded against Mumbai City FC in Kerala's last game while Iain Hume sat out of the tie.
The visitors, playing their first away game of the season, suffered an early set back in terms of Dimitar Berbatov having to leave the pitch due to what looked like a muscle pull as Milan Singh was introduced in his place.
However, the Blasters were the first to bulge the net when Jackichand Singh's cross from the right saw Bruno Pinheiro and Seriton Fernandes fail to pick the run of the Sifneos. The Dutchman's shot was aimed straight at Laxmikant Kattimani, but the home team's custodian let it slip under his feet.
FC Goa's reply came soon after as referee Ramaswamy Srikrishna allowed an advantage following Courage Pekusen's foul on Brandon Fernandes. Ahmed Jahouh squared it to Edu Bedia who in turn spotted Narayan Das on the left flank before Lanzarote converted with a calm finish from the far side.
Lanzarote followed that up with an incredible solo effort from inside the box where none among Arata Izumi, Sandesh Jhingan and Nemanja Lakic-Pesic could close him down before the Spaniard slotted the ball past Rachubka.
In fact ,the opportunity had opened up after the Kerala goalkeeper's pass to Arata was intercepted by Coro and simultaneously put in the path of the goalscorer.
Another defensive error, this time at FC Goa's end with a mispass from Mohammed Ali that fell for Milan Singh, resulted in the eventual pass inside the box and it slotted in past Kattimani by Jackichand to level things up again.
Sifneos and Brandon came close to increasing the scoreline for their respective sides through their efforts but the scores remained level at 2-2 going into the break.
Come the second half and Coro handed a three-goal lead to FC Goa within a span of minutes. The first came after he smashed the ball past Rachubka after a through ball that intersected Jhingan and Lakic-Pesic. The Spaniard then took the ball past the same defensive pair and chipped it over the hapless goalkeeper who had to fish the ball out of his net once again as Coro completed his hat-trick after nodding in a cross from Lanzarote.
With Goa enjoying 67 per cent possession, Meulensteen threw in striker Karan Sawhney for Loken as Kerala made their intentions clear. However, Lobera too made a change with an objective to break the opponent's play in midfield as he introduced Pronay Halder in place of Narayan Das.
Almost immediately, Halder could have gotten an assist. Edu Bedia left the ball as it rolled towards Lanzarote on the right side of the box. The Spaniard's curling effort had Rachubka beaten in his area but it rebounded off the top left corner. That was after Mandar Rao Dessai's right footed effort from outside the box had just about been kept out by Rachubka.
A few crucial saves by Kattimani did a world of good to the Goan goalkeeper's confidence after letting in the first first goal the way he did. The hosts also had their share of luck when Sifneos' attempt came off the crossbar before the custodian had to deny Pekuson's shot at goal late in the game.
There was another attempt by Manuel Arana, who had replaced Lanzarote, but his lob went over the post during stoppage time. Halder's pile-driver was also kept out by Rachubka to prevent further humiliation to Kerala Blasters.
