Fans have clashed with police outside Anfield ahead of Liverpool's Champions League clash with Rangers.
At least one arrest has already been made after disturbances broke out around two hours before the game is scheduled to start. Merseyside Police put a plan in place for the fixture to ensure the first-ever meeting between these two sides in Europe goes ahead smoothly.
Superintendent Dawn McNally discussed details of the plan with the Liverpool Echo, explaining there would be "additional resources in the city the night before the game" and "a large number of officers on duty" on the day. She said: "We have been working closely with Liverpool and Rangers football clubs and supporters' groups ahead of tomorrow night's match at Anfield.
"Merseyside Police has a history of successfully supporting large sporting events and a comprehensive policing plan is in place to ensure the match goes ahead smoothly and everyone attending has a safe and enjoyable time.
"The history between Liverpool and Rangers supporters is good but as with any high-profile European football match, we will ensure there is an adequate number of officers in and around the city centre to monitor and engage with fans from both sides to ensure their safe passage to Anfield.
"Merseyside Police has also linked in with partners including Liverpool Football Club and Liverpool City Council to ensure the event passes smoothly and that there is minimum disruption and congestion to roads and pedestrians as well as local businesses."
This Tuesday incredibly marks the first time Liverpool face Rangers in a competitive fixture, with the Premier League side favourites to secure the points.
But Rangers go into the match in good form having thumped Hearts 4-0 last time out while Liverpool had to settle for a point against Brighton.
Reds boss Jurgen Klopp said ahead of the game: "Good football team, well coached, exceptional European season last year obviously.
"Qualifying for the Champions League a big, big, big, big achievement. I saw obviously the last game against Hearts. I saw more games but now, especially the last one.
"Really good football team and that's what we have to prepare for. And a team who have had results they didn't want, so that's what they want to change definitely.
"So, we expect a proper fight, a real fight, to be honest, and that's what we prepare for."
