The England international signed for Liverpool in 2009 in a deal estimated to be worth around £17 million. Former Portsmouth chief executive Peter Storrie negotiated the sale, and the fullback signed a four-year contract with the Premier League title clause included.
The story has been doing the rounds on Twitter over the past few days with Liverpool pushing ever closer to claiming their first Premier League crown. It was officially broke by chief sports writer Neil Allen of The News in Portsmouth, and has since been confirmed by Sky Sports reporter Amy Lewis.
Portsmouth, however, who are fighting for survival in the bottom half of League two, are refusing to comment on reports - perhaps not wanting to put a jinx on the prospect of a huge windfall.
Johnson, now 29, was a fan favourite at Fratton Park and over the course of three seasons, one as a loanee, made 99 appearances including the 2008 FA Cup final win over Cardiff. He managed four goals during his spell at Portsmouth, including a left-foot screamer against Hull in November 2008 that won the goal of the season award.
Liverpool are currently leading the race for the Premier League title, two points clear of second placed Chelsea, and four clear of Manuel Pellegrini’s Manchester City, who have two games in hand of the table toppers.
Should Liverpool win the title, they will pocket £15 million in prize money in addition to TV money and Premier League share money. Last seasons’ champions Manchester United raked in a total of £61.4 million. So Liverpool won't have trouble parting with a million if they are crowned champions, and if there were ever a club and fan base that deserved a bit of good fortune, it's Portsmouth.
