Olivier Giroud's hat-trick helped Milan maintain their push for Champions League qualification as they cruised to a comfortable 5-1 victory over Serie A's bottom club Sampdoria.

Giroud netted a first-half double and added a third following the break at San Siro on Saturday to keep the Rossoneri – who were licking their wounds after falling short to rivals Inter in the Champions League semi-finals – on track in their pursuit of a place in the top four.

Rafael Leao opened the scoring, though already-relegated Sampdoria restored parity through veteran forward Fabio Quagliarella.

But after Giroud's quickfire double, Brahim Diaz got in on the act before the France forward rounded off his hat-trick to cap an emphatic success.

Milan needed just nine minutes to carve open their visitors, with Leao latching onto Diaz's lob delivery outside the box before slotting a low finish past Nicola Ravaglia.

Sampdoria seized a shock equaliser against the run of play when Quagliarella drilled an Alessandro Zanoli cut-back beyond Mike Maignan, but parity was short-lived.

Giroud restored Milan's lead three minutes later when he nodded Diaz's cross in, before converting a penalty after Leao was felled by Koray Gunter.

Any comeback hopes Sampdoria may have harboured heading into the second half were extinguished in the 63rd minute, with Diaz tucking home from Sandro Tonali's square pass.

Giroud completed his hat-trick five minutes later, with the striker shrugging off Bram Nuytinck to smash home at close-range and seal the deal.

What does it mean? Milan bounce back

After exiting the Champions League in dour fashion to their biggest rivals, the Rossoneri needed a response to keep their hopes of playing in UEFA's flagship club competition next season alive.

They did so in emphatic fashion, and while critics may deride Sampdoria as an easy test, they nevertheless regained some crucial flair and fluency in their game, having 19 shots and getting nine of them on target.

Leao lords it up

Giroud might take the headlines, but Leao was once again a standout performer.

Leao has now been involved in 21 goals this term, his best in a single Serie A season. It is the first time a Milan player has tallied more than 20 involvements in one campaign since Zlatan Ibrahimovic in 2011-12.

Milan will do well to keep hold of the Portugal international.

Quagliarella keeps on going

A lone consolation in the end as Milan raced away with the game, the Sampdoria captain's finish nevertheless saw him extend his impressive scoring record.

He has now netted in 18 different Serie A campaigns, making him just the fourth man to do so. The outright record is held by Francesco Totti, with 23.
