After BVB met Barcelona in Group F in the UCL group stage, BVB mocked Barca on twitter.
"Time to practice our corners," BVB wrote on Twitter.
On May 7th, 2019, Liverpool eliminated Barcelona with an epic comeback. Alexander-Arnold assisted Divock Origi with a 'magical' corner to help the Reds seal the 4-0 victory in Anfield, which ensured Liverpool to eliminate Barca.
