Having seen a late winner in Monday's (AEST) ill-tempered draw with Salernitana, Arkadiusz Milik took just four minutes to open the scoring, flicking past Odisseas Vlachodimos to seemingly put the host in control.

However, a Joao Mario levelled things up with a first-half penalty and Neres volleyed in the winner after 55 minutes, putting Benfica joint-top of the Group H alongside Paris Saint-Germain.

There were chances for a late equaliser, Dusan Vlahovic seeing an effort disallowed and Bremer squandering a golden opportunity to leave the pressure mounting upon Massimiliano Allegri.

Juve raced out the blocks in a frantic start, with Milik's glancing header from Leandro Paredes' right-wing cross finding the bottom-left corner to open the scoring.

Filip Kostic drilled just wide from Juan Cuadrado's looping delivery before Goncalo Ramos should have restored parity but directed straight at Mattia Perin with a close-range header.

Rafa struck the right-hand post with a curling effort but Benfica's dominance soon paid dividends when Joao Mario converted his penalty, which was awarded after a VAR check for a Fabio Miretti foul on Ramos.

Vlachodimos parried away a swerving Milik shot after the interval before Neres smashed a left-footed volley into the bottom-left corner following Perin's save from Rafa's drive.

Perin was again required to push away a fizzing Rafa strike before the Juve goalkeeper showed smart reflexes to keep out a Neres strike as Benfica threatened to extend their lead.

Vlahovic thought he had snatched a late equaliser, only for the offside flag to go up after Mattia De Scigilo's cross from the left, before Bremer blazed a golden opportunity over with just three minutes left.
