VILLARREAL, Spain (AP) — A record-breaking start. A goal for a teenage debutant. Most importantly, another big win.

It was the perfect night for Paris Saint-Germain in the Champions League.

The defending champion swept to a 6-0 rout of Villarreal on Tuesday to continue the 100% start to its bid for a third straight title.

It was pretty much all over after 17 minutes, with four goals sinking the Yellow Submarine — nickname of the Spanish hosts — in record time.

When Fabian Ruiz slammed home a shot for 4-0 after earlier strikes by Joao Neves, Desire Doue and Senny Mayulu, it was the fastest any team had reached four goals in a Champions League game, according to UEFA.

Ruiz scored his second of the night in the 50th and PSG's biggest win of its title defense was capped by a 78th-minute goal from David Boly, a 17-year-old defender who had come on for his Champions League debut as a substitute four minutes earlier.

PSG had faced a test of its squad strength with four of its best players missing for the trip to Spain, but coped just fine.

Ousmane Dembele, Marquinhos and Nuno Mendes were all missing because of thigh injuries, along with long-term absentee Khvicha Kvaratskhelia (ruptured ACL).

It didn't stop PSG easing to a 10th straight win in all competitions — and a fourth in a row to open the Champions League — though Villarreal contributed to its own downfall with dreadful defending.

The first three goals stemmed from mistakes by the home team as it played out from the back or got dispossessed in its own half.

According to UEFA, the previous fastest time a team had reached four goals in a Champions League game was 20 minutes, by Real Madrid in a 6-2 home win against Dinamo Zagreb in 2011.
