Liverpool owner John Henry has been as decisive as possible in his stance on key player Luis Suarez' request to leave the club, stating outright he is not for sale.
Henry will have been well advised Suarez is not the type of person to take not getting his own way very well, but the American owner has seen it all before.
As owner of Major League Baseball team the Boston Red Sox, he has been around the block a few times and dealt with big ego's on huge salaries.
Suarez, while a challenge for a manager like Brendan Rodgers who has never been in this sort of situation before, should be a cakewalk for John Henry compared to former Red Sox designated hitter, Manny Ramirez.
Ramirez was a key man in the Red Sox 2007 World Series win, and over the course of his baseball career recorded more than 500 home runs.
A year later it all turned sour. Ramirez became unhappy in Boston, and began showing it on and off the field.
While Liverpool's Luis Suarez decided to bite an opponent, Ramirez decided to attack members of his own organisation.
He got into a physical altercation with teammate Kevin Youklis during a contest with the Tampa Bay Rays after a heated exchange got out of control. Ramirez was caught on camera taking a swing at Youklis, and the rest of the team had to rush to break up the fight.
Months later, Ramirez had asked the Red Sox' secretary to meet a last minute request to find tickets for 16 visiting friends and family, which they were unable to meet at short notice.
Ramirez in anger pushed the 64-year-old secretary to the ground, yelling at him 'do your job'. He was fined by the incident, and the unpleasantness between player and team was reaching new levels.
Then it took a further turn. Ramirez pulled out of a number of games citing a knee injury, although many at the organisation saw it as a petty act purely because of a contract dispute, when he believed him healthy enough to play.
When he did make it onto the field, he was lacklustre and accused of putting in half the effort, and that was when the Red Sox management had enough.
He was traded to the LA Dodgers, and had an instant impact, finishing fourth in the vote for the MVP. But then his career turned sour again.
Ramirez recorded a positive drugs test and was handed a 50 game ban, and when he returned, a second positive test effectively wrote off his career. He retired only to recently make a comeback at the age of 41 with the Texas Rangers.
If Luis Suarez is to trump him as John Henry's biggest headache, the Uruguayan has a long way to go yet.
