Barry and Margaret Mizen MBEs paid a special visit to Millwall on Thursday ahead of Saturday's visit of Charlton Athletic, which marks the club's annual 'Jimmy's Day'.
Each season Millwall dedicates a fixture to the 'For Jimmy' foundation, which was set up by Barry and Margaret following the murder of their son Jimmy, a Lions fan, in May 2008.
On Thursday, the duo visited the Lions Centre, home of Millwall Community Trust, to give moving speeches to students on the Post-16 Football and Education course and to also watch the first - and now to become annual - Jimmy Mizen Cup, which was played out between children from schools in the local area.
"It's been an incredibly wonderful day to see all the children playing together in Jimmy’s memory," Margaret Mizen told millwallfc.co.uk.
"It has just made us as a family really proud, and it’s great for the young people. The fact it is going to be an annual event and how great it is for the young people, I’m very humbled."
Saturday's game will also see Charlton fan Rob Knox honoured, another young man who was sadly killed in May 2008.
Margaret explained how, despite the local rivalry that will be present on the pitch and in the stands this weekend, it is important to put that to one side when remembering.
"I think sometimes you do have to put rivalry to one side, and for me it is really important for everyone to come together when they play in memory of Jimmy and in memory of Rob.
"As families, we are all humbled by the clubs and the fans with the way they support us. I’m really looking forward to Saturday, it’s going to be a great day.
"Rob was killed just two weeks after Jimmy, and we’ve got to know his family really well. They also work tirelessly to prevent the violent crime that’s going on, so the fact we can come together as two families with the fans’ support – nothing could be better."
Meanwhile, Sean Daly, CEO of MCT, added with regards to the competition: "It’s great to bring all the schools together, it gives the community cohesion and acknowledges the memory of Jimmy Mizen and Rob Knox.
"It's great that the kids have been able to play football with young boys and girls from other boroughs – Greenwich and Bexley – to see that everyone enjoys football. Football has the power to break down barriers, because it’s common ground – everyone just wants to play, and we’re all here [on Thursday] celebrating the lives of Jimmy and Rob.
"This tournament has probably been the highlight of our year as a Community Trust so far, as well as Margaret and Barry’s. Of course, as well as Community Day, for us to be able to host this as we look to do every year, it’s brilliant. We engage with so many young people, we’ve got to keep that momentum going with them."
Bucket collections will be held around the ground before kick-off on Saturday 'For Jimmy', whilst both Millwall and Charlton will warm-up in special 'For Jimmy' T-shirts during the warm-up, brandishing the slogan 'forgiveness, peace and hope' across them.
Barry will also be on hand to address the sold out crowd shortly before kick-off at The Den.
