That will see both sides ditch their home shirts for the Boxing Day game at Fratton Park to raise awareness of homelessness in the UK and help raise money for Shelter.
Homelessness has risen dramatically over the past decade.
The pandemic has shown us the importance of having a safe home like never before – yet more than 180,000 households have been made homeless since March 2020.
With a tough winter ahead, even more people could lose their homes.
So Shelter’s frontline services are working harder than ever to help people find and keep a home this Christmas, but they can’t do it alone.
Whether watching from the terraces or gathered round the living room TV, football understands what home means.
Home gives all fans a sense of identity, belonging and, above all, community.
We encourage supporters to ditch their home shirts, too.
For the first time, we urge you to get behind the Blues, by not wearing blue.
