According to Football Insider, Southampton are confident that Fraser Forster's value will rocket to more than £20m by the time his campaign on loan at Celtic is over.

What's the word, then?

Well, the 6 foot 7 goalkeeper described as a 'man-mountain' by The Times recently seems to have rediscovered his form whilst out on loan with his former side - Scottish giants Celtic.

Reunited with Neil Lennon, Forster has made 15 starts across all competitions for the Bhoys since signing on a season-long loan deal back in the summer.

Across these outings, the 31-year-old has conceded just ten goals and has also registered seven clean sheets as he looks back to his commanding self.

However, the Saints' belief that his value will soar to over double the £10m that they spent on him back in 2016 is a ludicrous belief to hold.

There's no way Forster will be worth that

Despite the aforementioned statistics from Forster, which are undeniably impressive, a few things must be brought into the conversation to add a bit of necessary context.

Firstly, the Scottish League really isn't an accurate barometer of a footballer's quality and is arguably a weaker division that the Premier League - Football Insider report that a move back to England's top-flight is perhaps the more likely destination for Forster, with his £70k-a-week wages almost certainly putting him out of Celtic's reach.

Furthermore, what Premier League side would want to take the gamble of Forster given the way his career in England went before his departure?

The six-cap England international didn't play a single minute of Premier League football across 54 matches for the Saints during the 2017/18 and 2018/19 campaign, with his last outing for Southampton coming in a 3-0 loss against West Ham.

Forster was third-choice behind Alex McCarthy and Angus Gunn for almost two years, and is merely enjoying a mini-resurgence in a much weaker division.

Quite why Southampton think that will make him worth £20m is a mystery.
