Uefa have revealed the new match ball for the Champions League knockout phase as Arsenal await to discover their knockout opponents.

The European competition has undergone a huge change in the last year, with this season being the first time it was expanded and involving 36 teams. Not only were more teams involved than ever before this year, but the group stages were dispensed with, in favour of a league phase.

Arsenal won six of their eight games in the opening stage, finishing third in the standings - level on 19 points with Barcelona. The Gunners were one of three English teams to progress to the knockout stage, with Liverpool and Aston Villa also finishing in the top eight.

Mikel Arteta's side will take on the winners of either PSV Eindhoven vs Juventus or AC Milan vs Feyenoord. The last-16 draw will take place on Friday, February 21 after the two-legged play-offs conclude next week.

With the knockout ties set to be played on either March 4 or March 5, Uefa have unveiled their new adidas 'Pro Ball Munich' match ball. Dark green features predominantly around the ball while the white stars are accompanied by the pink adidas and Champions League logo.

"The design celebrates Munich's status as the gateway to the Bavarian Alps and features the Champions League stars in white alongside hexagons in a striking green and copper, a nod to the colours of the rooftops and buildings seen throughout the city," Uefa explained. "Within the green and copper block panels are small graphics celebrating some of Bavaria's most recognisable features – the Alps, the Palatine Lion, edelweiss flowers, the Waldlerhaus, the English Garden and hops, a popular crop in the region.

The ball is described as having a 'range of technical innovations' with the PRISMA surface delivering improved precision and swerve. The outer texture offers secure grip and complete control while the seamless construction has been built for ultimate performance.
