Ewa Pajor and Salma Paralluelo scored twice each in Oslo as Barcelona turned on the style in the second half to rout Lyon 4-0 and lift the Women's Champions League for a fourth time.

Pajor struck twice in the space of 15 minutes to put Barcelona in control before Paralluelo added some late gloss, firing in a superb strike in the 90th minute before rolling the ball past Christiane Endler in stoppage time as Lyon, eight-time winners of this competition, fell apart.

Lyon thought they had scored first when Lindsey Heaps tucked home after Wendie Renard's header was saved by Cata Coll 14 minutes in, but VAR intervened as Heaps was offside in the build-up.

Pajor's 10th goal of this Champions League campaign came 10 minutes in the second half when Patri Guijarro slipped the ball through and her angled finish beat Endler, and she doubled up in the 69th minute.

The chance appeared to have gone Claudio Pina missed the target from Esmee Brugts' cross, but Paralluelo kept the ball in and pulled it back for Pajor to rifle home.

As Lyon pushed further and further forward Barca punished them at the death. Paralluelo's first goal was a superb rising left-footed strike from the edge of the box, and Pajor then laid on her second goal when she squared for her team-mate to finish.
