Liverpool: Liverpool manager Jurgen Klopp called for a cauldron of an atmosphere when the European champions host Manchester City on Sunday, but warned fans against overstepping the line. City's team bus was damaged by thrown bottles ahead of their Champions League quarter-final, first leg at Anfield in April 2018. Liverpool were fined 20,000 euros ($22,000) by UEFA for that incident and publicly apologised to City.

But the rivalry on the field between the two sides has grown even more intense over the past 18 months after City pipped Liverpool to the Premier League title by a single point last season. "I'm a big believer of fan power -- in the stadium. That's completely different," said Klopp on the previous attack on City's bus. "That was a senseless thing. If somebody at Man City is concerned still, then it's our fault.
