Carragher mistake gifted Zenit early lead, but goals from Suarez and Allen give Reds hope.
Hulk takes advantage of poor Carragher backpass and slides the ball pass Reina to give the Russian side the early lead.
Suarez then draws Liverpool level with this free kick, although questions will be asked about the setup of Zenit’s wall.
Joe Allen then bundled in Liverpool’s second with five minutes left to go in the first half.
Liverpool still have it all to do, and will need a strong second half to grab the two more goals needed to see off Zenit, and produced another memorable Euopean night for Liverpool.
