MERSEYSIDE Police have vowed to clamp down on the use of flares and other pyrotechnics ahead of Liverpool's Champions League semi-final clash with Roma at Anfield tomorrow.
Home fans are planning to meet around the ground from approximately 5pm for a "Roma coach greeting".
A message posted on Twitter announcing the details of the gathering read: "We saw how the atmosphere helped the boys against Man City.
"The support we give our players is something money can't buy.
"Lets get behind the boys and help them on to Kiev. Bring your flags and banners, your pyros and your pints."
Windows were smashed as bottles and cans were thrown at the bus carrying Pep Guardiola and his team to the quarter final at Anfield earlier this month.
Shocking footage from inside the Manchester City coach showed objects hitting the windscreen and side windows as one of the glass panels was smashed.
Police are now keeping a close eye on events and want to make sure that there are no fireworks used tomorrow night.

According to the Mail, Chief superintendent Dave Charnock said: "While recognising that some supporters feel they can add to the atmosphere of the occasion, the use of flares and other pyrotechnics at and around football matches is a concern.
"We are expecting a vibrant atmosphere at Tuesday's match.
"But our intention is at the end of the day we will be talking about the game and what happened on the pitch as opposed to off the pitch.
"As always, my officers will be dealing with the fans, as they would expect to be treated themselves.
"Our policing style will be firm, fair and friendly, but we will take action where necessary, against those individuals who may seek to cause problems or misbehave and spoil the evening for the majority of supporters."
