Flags have become as much a part of Champions League nights at the Bridge as the pre-kick-off anthem and referees from foreign parts and 30,000 new flags will be placed in the stands for next Wednesday night.
There will also be the new giants flags you may have noticed flying high in recent weeks and supporters can play their part by adding to the colour and by filling the stadium early to build the atmosphere prior to the whistle.
This season, one free flag has been placed at every other seat but against Liverpool, there will be a flag awaiting at each seat in the regular parts of the stadium.
'With it being the last Champions League game of the season at home, but hopefully not our last Champions League game, we want to have a fantastic atmosphere,' says Wesley Barton, stadium tours supervisor who is much-involved in the flag project.
'It creates a bit of atmosphere seeing that sea of blue when the players come out and it is great for TV as well.
'Anything to try to inspire the players is worth it. We have heard the players do like it and anything to give them that extra one per cent is valuable.'
At the last few matches there has been a new addition to the flags, based on successful displays originally seen in stadia overseas.
'We now have a few giant flags waved in front of the West Stand. We trialled them for a couple of Premier League games to use them for this game [liverpool]. It is some of the tour guides that actually wave them,' explains Barton.
