According to Football Insider, Southampton believe they have a £25m-plus asset on their hands in Fraser Forster, following his Betfred Cup final heroics against Rangers.

What's the word, then?

Well, the Saints believe that the 31-year-old's value is soaring while he is on loan at Celtic.

Forster returned to Celtic Park on a season-long loan deal back in the summer, and has made 20 appearances in total this term under Neil Lennon, while keeping nine clean sheets and conceding just 13 goals in total.

The 6 foot 7 glovesman practically won the Betfred Cup final single-handedly for the Bhoys on Sunday afternoon, pulling off a number of heroic stops - Forster also saved Alfredo Morelos' second-half penalty.

Despite that, Southampton are showing further signs of their delusion.

Skewed valuation of Forster

Midway through November, another report from Football Insider revealed that Southampton believed Forster's value would go beyond £20m by the end of the current campaign, a belief that we outlined as slightly delusional.

Why? Well, with the upmost respect, Scottish football isn't of the highest quality around, and is almost certainly a weaker division than the Premier League.

Additionally, the way in which Forster's last few years at St Mary's went surely won't fill any potential buyers with confidence.

The England international slipped to third place in the pecking order behind Alex McCarthy and Angus Gunn, failing to play a single second of Premier League football across 54 fixtures for the Saints during the 2017/18 and 2018/19 campaigns.

With that in mind, the more recent report from Football Insider which states that Southampton believe Forster is now a £25m-plus asset only reinforces their delusion over the value of their out-on-loan goalkeeper, who really isn't worth that much despite impressive performances in Scotland.

A few Shot-stoppers to have cost £25m and over are marquee names such as Gianluigi Buffon, Alisson Becker and Kepa Arrizabalaga, while England No.1 Jordan Pickford cost £25m as recently as 2017 - there is no way that the Saints will gather as much money as they think they will for Forster.
