PSG and Napoli rack up the goals on entertaining Champions League evening

It was no more than PSG deserved after dominating throughout, with Cavani running the show.

Ludogorets' Brazilian left back Natanael opened the scoring with a stunning free kick in the 16th minute, but the visitors soon seized the initiative, enjoying more of the possession and levelling the score when Blaise Matuidi latched on to Marco Verratti's through-ball.

The visitors dominated after the break and Cavani, who also scored in PSG's 1-1 draw against Arsenal in their opening match, netted two times in the space of four minutes.

The Uruguayan striker made it 2-1 with a firm header from Angel Di Maria's clever assist from free kick and added another one from close range only a minute after PSG keeper Alphonse Areola saved Cosmin Moti's penalty.

The result puts PSG top of the group with four points from two games, ahead of Arsenal on goal difference after Arsene Wenger's side secured a 2-0 home win over FC Basel.

Over in Naples, Gonzalo Higuain was little more than a distant memory as Napoli produced a rousing display to beat last season's quarter-finalists Benfica 4-2 in Group B.

Midfielder Marek Hamsik headed Napoli in front after 21 minutes before a devastating spell of three goals in eight minutes early in the second half left the Portuguese champions reeling.

Dries Mertens curled in a free kick in the 51st minute, Arkadiusz Milik swept home a penalty and Mertens struck again just before the hour.

Benfica enjoyed a later flurry with Goncalo Guedes and Eduardo Salvio making the scoreline more respectable, but Napoli - unbeaten in all competitions this season - have six points from their two games in Group B while Benfica have one.

In other results on a thrilling evening across Europe, Besiktas were held 1-1 by Dynamo Kiev and FC Rostov were twice pegged back by PSVEindhoven in a 2-2 draw.
