Manchester United was defeated 3-0 (4-0) in an away game against Barcelona in the Champions League quarter finals second leg, yesterday night.
During the game, David de Gea's mistake led to Lionel Messi's second goal in the 20th minute.
And apparently de Gea's mistake reminded the fans about Loris Karius as his name was trending on Twitter.

Karius' made mistakes in the Champions League 2017/18 final which cost the Reds an UCL title as Liverpool lost 3-1 to Real Madrid.
