Watching England play is one of life's most stressful events, research has suggested.
A poll of 6,000 Britons by hotel chain Travelodge found 40% of men said seeing England play was worse than a job interview, 15% said it was more stressful than getting married and 25% said moving house was easier.
Meanwhile, a study by Santander Current Accounts estimated Britons would collectively spend £260 million on flowers, restaurant meals, holidays and other peace-offerings in a bid to make up for neglecting their other half while watching the World Cup.
The poll of 2,000 people found 10% predicted the football would cause an argument with their partner.
A Western Union poll of 462 members of the Football Supporters' Federation (FSF), found the average fan travelling to watch the World Cup had spent between £4,000 and £5,000 on watching England through the group stages.
But following their team to the final would cost a further £4,000 each - a price few have budgeted for, the poll said.
Nearly one in three (30%) said they would put the extra expense on credit cards, 18% would dip into savings and 9% would rely on hand-outs from friends and family.
Michael Brunskill, of the FSF, said: "Being a football fan is a costly business and the FSF always advises fans to plan in advance so we hope that most won't be returning to the UK too out of pocket - whenever this may be.
"However, with England squad members on an average wage of £125,000 per week, we hope that their World Cup performance will offer good value for money for fans.
