Lionel Messi became the record goalscorer in Champions League history as he led Barcelona to a 4-0 victory over APOEL Nicosia.
After Luis Suarez had opened the scoring with his first goal for Barca, the Argentina international struck for the 72nd time in the competition, in the process eclipsing the haul of former Real Madrid star Raul, and then added two more to set up a grandstand finish to Group F.

Edinson Cavani helped to maintain PSG’s challenge with a double in a 3-1 home win over Ajax, who now host Cypriots APOEL needing a point to clinch a Europa League spot.
Messi, who also became the all-time record Primera Division scorer at the weekend, was not the only hat-trick hero with fellow Argentinian Sergio Aguero matching his feat on a dramatic night at the Etihad Stadium.
The Manchester City striker had fired his side into an early lead from the penalty spot after Bayern Munich defender Medhi Benatia was sent off for bringing him down, and after Xabi Alonso and Robert Lewandowski had put the visitors ahead, struck twice at the death to snatch a 3-2 win.
City will now head for Roma engaged in a three-way battle for second place in Group E behind the Germans after the Italians drew 1-1 at CSKA Moscow.

That victory, coupled with Shakhtar Donetsk’s 1-0 home defeat by Athletic Bilbao, which came courtesy of defender Mikel San Jose’s lone strike, means they and the Ukraine club will progress regardless of which of them comes out on top at the Estadio do Dragao next month.
