The world of football is in mourning after one of its biggest characters - Jack Charlton - passed away on Saturday.

England World Cup hero Jack died on Saturday morning following a battle with lymphoma and dementia with his family by his side.

Jack spent his entire 21-year playing career at Leeds, making a joint club record 773 appearances, before retiring as a player in 1973 and going on to enjoy a successful and colourful career as a manager.

One of English football's most popular and larger-than-life characters, he had spells in charge of Sheffield Wednesday, Middlesbrough, Newcastle   and the Republic of Ireland, who he guided to their first major finals at Euro 88 and two more in the space of 10 years.

The statement from Charlton's family read: "Jack died peacefully on Friday 10 July at the age of 85. He was at home in Northumberland, with his family by his side.

"We cannot express how proud we are of the extraordinary life he led and the pleasure he brought to so many people in different countries and from all walks of life.

"He was a thoroughly honest, kind, funny and genuine man who always had time for people.

"His loss will leave a huge hole in all our lives but we are thankful for a lifetime of happy memories."

Jack spent his entire 21 year playing career at Leeds and making a record 773 appearances for the Yorkshire club.

After retiring as a player he had spells in charge of Sheffield Wednesday, Middlesbrough,   Newcastle  and the Republic of Ireland, who he guided to their first major finals at Euro 88 and two more in the space of 10 years.

Despite Jack's incredible club and mangerial achievements for many of his fans his finest moment was lifting the World Cup trophy alongside brother Bobby and his England team-mates in 1966.

The England football team tweeted: ''We are devastated by the news that Jack Charlton, a member of our World Cup-winning team of 1966, has passed away. ''Our deepest sympathies are with Jack's family, friends and former clubs.''

The image of the pair hugging as Bobby told his older brother "nobody can ever take this moment away from us" is one of the most famous of the World Cup campaign.

However, behind the relationship between the country's most famous footballing brothers was anything by harmonious.

The pair, despite sharing a bed when they were children, were said to have vastly different personalities.

Jack was outgoing and confident while Bobby was shy and quiet - and their differences only seemed to become more marked as they reached adulthood.

Jack accused Bobby of failing to visit their devoted mum, Cissie, when she was dying.

He claimed there had been a clash between Bobby's wife Norma and Cissie which caused the rift. he also said his brother's wife was stand-offish and difficult.

More than a decade later, the feud between the brothers still hadn't healed with Bobby released his autobiography with his side of the story.

Bobby wrote: "My wife is a very strong character and does not suffer fools gladly. I am not suggesting my mother was a fool. There was a clash and it just never went away really.

"Jack came out in the newspapers saying things about my wife that were absolutely disgraceful. Nonsense. Ask anybody that ever met my wife: 'hoity-toity' is not a word they'd use.

"My brother made a big mistake. I don't understand why he did it. He could not possibly have known her and said what he said."

The pair refused to speak for decades and were only finally reunited when they both attended the funeral of fellow 1966 hero, Ray Wilson.

But what sparked the war with the two icons of football?

Back in 1957 the Charlton brothers had been the best of friends with Bobby even serving as Jack's best man at his wedding to wife, Pat Kemp.

They enjoyed regular games of golf and couldn't have been closer, with Jack admitting his brother was his "best friend".

Then, following the Munich Disaster in February 1958, something changed in the relationship between the two men.

The crash killed half of the travelling team, with Bobby one of the lucky survivors - however, he was haunted by feelings of guilt for the rest of his life.

Jack said: "I saw a big change in our kid from that day on. He stopped smiling, a trait which continues to this day."

The tragedy also dramatically altered Bobby's relationship with his devoted mum, Cissie, who had been instrumental in pushing his football career.

In the aftermath of the disaster Cissie travelled to Manchester to volunteer at the club, helping in any way she could.

Harry Gregg, a former United goalkeeper and another survivor of the crash, said: "I don't think Bobby was too happy about her being in the offices there. He was slightly embarrassed by her."

Then, the rift between the warring brothers deepened when Bobby tied the knot with his wife, Normal, in 1961.

It had been love at first sight for Bobby but it seemed his mother, Cissie, didn't agree and disapproved of the match.

She said: "I do not accept my daughter-in-law. There is a rift and it is up to her to come to me. But I don't want to make up. It has gone on too long."

Norma has since claimed her and Bobby's children never received birthday cards or presents from their grandmother.

It left Bobby with no choice but to choose between his wife and his mother and he chose the family he had built for himself.

The decision led to a huge rift with the rest of his family.

Bobby and Jack's father, Bob, reportedly told his family on his death bed to throw any flowers his younger son sent "on the fire".

Despite presenting his younger brother with the BBC Sports Personality of the Year's Lifetime Achievement Award in 2008, it would be another decade before the two Charlton's were finally pictured together at Wilson's funeral.

Left back Wilson died in May, 2018, aged 83 following a battle with Alzheimer’s disease for several years.

He was often described as one of the forgotten members of the squad as he wasn't one to seek the limelight but was a vital part of the victorious squad.
