A die-hard Manchester City supporter is set to make the ultimate sacrifice for charity – by getting a tattoo of the Manchester United badge.

Lifelong fan Chris Worthington, of Coare Street, Macclesfield , has pledged to have his arch enemy’s logo inked on his forearm if he can raise £1,500.

The gesture is to thank the charity When You Wish Upon A Star, which supported his seven-year-old daughter Poppy’s battle with a brain tumour.

Chris, 45, said: “I wanted to raise some money to thank them and this idea just popped into my head.

“I’m not in shape to run a marathon and I couldn’t think of anything more personally painful than a United tattoo on me for the rest of my life.”

Despite being born and bred in Macclesfield, and having a Manchester United-supporting dad, the custody officer for the immigration service has always loved the Sky Blues.

Now he is bracing himself for some stick from fellow City supporters – as the tattoo will be easy to spot, with it planned to be the size of a jam jar lid.

He added: “I have no other tattoos, so this is going to be quite a thing.

“I didn’t want it to be hidden away, so I’m committed to it being on my forearm so it is obvious.

“Some of my City-supporting friends have refused to pay, unless I reach my target, so it looks like I’ll be appealing to those devious United fans to help me.”

Poppy was diagnosed with a brain tumour in July 2010 after she suffered from dizziness.

The tumour caused a build-up of fluid on her brain resulting in her loss of balance and created a fear of a dizzying ride on the swings.

Mum Rachel, 37, said: “It was quite scary. We had an MRI scan and within 20 minutes they came back and said she had a brain tumour in a very dangerous area – we were given little hope.”

But nearly a year on and following an operation to drain the fluid at Manchester Children’s Hospital, Poppy is living her life to the full. The tumour is likely to stay with the Bollinbrook Primary School pupil, but it has not grown bigger since diagnosis.

Rachel added: “It won’t disappear and won’t shrink, but there’s every chance that it has caused all the problems it’s going to cause. She’s doing really well and we are very proud of her.”
