The goal machines of Bayern Munich, Chelsea and Shakhtar Donetsk cranked into top gear on Tuesday as the Champions League captivated its continental audience with a record 40 goals in one eight-game night.

Bayern, who humbled Roma 7-1, Chelsea, who beat Maribor 6-0, and Shakhtar, who enjoyed a 7-0 win at Bate Borisov, contributed 20 between them on an evening to forget for defenders and goalkeepers alike.

Bayern 7 - 1 Roma

Ukraine's Shakhtar became the first team to score six times in the first half of a Champions League match, and their victory was the joint-best for an away side.

Shakhtar's Brazilian striker Luiz Adriano became the first player to score four before halftime - and at 17 minutes he now holds the competition record for the quickest four-goal tally.

He added another late on to join Lionel Messi as the only players to have netted five times in a Champions League outing.

Messi scored once in Barcelona's 3-1 victory over Ajax to pull level with Cristiano Ronaldo on 69 Champions League goals, two behind all-time leading scorer Raul.

Chelsea's win against Maribor was their record victory in the Champions League.
