The striker returned from injury in sensational style as his treble, along with a strike from Edinson Cavani and an own goal, saw the champion romp to victory.Zlatan Ibrahimovic hit a hat trick on his return from injury as Paris Saint-Germain thrashed Saint-Etienne 5-0 on Sunday.
Saint-Etienne goalkeeper Ruffier miscontrolled a simple back pass from Jeremy Clement in the 24th minute and was unable to prevent it from crossing the line before he desperately hacked it away, with only a sympathetic handshake from Ibrahimovic to console him.
That set the tone for a miserable night for the visiting side, which was completely outplayed in the French capital.

Ibrahimovic opened his account shortly before halftime with a thumping header and the Sweden international – returning from a rib muscle injury – added two more goals in the second half to take his league tally to five for the campaign.
Those goals after the interval sandwiched a spectacular Edinson Cavani strike as PSG cruised to a resounding victory.
Making PSG's win more impressive was the absence of key men Thiago Silva and Yohan Cabaye, through injury and suspension respectively, while for Saint-Etienne, the result ended an unbeaten start to the campaign.
