French champions Paris Saint-Germain won 4-1 at Le Havre on Friday, capitalising on a late collapse by the hosts to get their Ligue 1 season off to an excellent start.

PSG opened the scoring after three minutes when Gonçalo Ramos found Lee Kang-in inside the box and he sent a left-foot shot into the net.

The visitors' joy was short-lived, however, as Ramos was hurt in a challenge and the Portuguese international had to be replaced by Randal Kolo Muani.

The hosts shocked PSG after the break as Gautier Lloris equalised three minutes in, before Josué Casimir's goal was disallowed following a VAR decision for handball in the build-up.

Five minutes before the end, the Le Havre defence went missing.

Ousmane Dembélé headed home five minutes from time, Bradley Barcola added a third and Kolo Muani completed the rout from the penalty spot.
