Former Newcastle boss John Carver has spoken to BBC Sport's Match of the Day 2 Extra about his time working with Fraser Forster at St. James' Park.
Forster, 27, is on an incredible run of clean sheets in the Premier League, as having recovered from a long-term knee injury, Forster has yet to concede a goal in his six appearances this season.
It's a remarkable run of form for Forster and the Southampton defence, and the shot stopper is now piling the pressure on England duo Joe Hart and Jack Butland ahead of Euro 2016 this summer.
The plaudits have been pouring in for Forster during this six-game run without conceding a goal, as it has seen Southampton drop just two points in that time, catapulting Ronald Koeman's men up the Premier League table.
One club who must be gutted to see Forster impressing so much is Newcastle United, given that they let the giant goalkeeper leave the club for Celtic in 2012, without ever giving him a first-team appearance after coming up through the ranks.
BBC Sport reported the fee at the time was just £2m, and Newcastle fans may be questioning why decision makers at St. James' Park allowed a homegrown player to leave, when the club preferred to go with Tim Krul as first choice goalkeeper instead.
Now, former Newcastle boss John Carver has told Match of the Day 2 Extra about Forster's time as a youngster with the Magpies, telling a bizarre story about how he was signed from a local grammar school.
Carver also claims that Forster has been 'immense' recently, stating that it's great to see him develop so much as something of a late bloomer.
"He's been immense with six clean sheets," said Carver. "I actually signed him! When Graeme Souness came into the football club, I became the academy director. We were playing a youth cup match, and I didn't have a reserve goalkeeper, so I said to the scouts 'Get out there and find me a goalkeeper' - just as cover! So a guy called Jimmy Blackhall went out there, went to the Royal Grammar School - which was a rugby school, not a football school - and come across Fraser."
"When he came through the door, he couldn't catch the ball, his co-ordination was all over the place. He's developed into one of the best goalkeepers in the country, but he's gone from rags to riches. He wasn't 14, 15 or 16, he was about 17 or 18 when he came to the football club, so he was a late developer. He was given the opportunity, and he's been a huge factor in Southampton's success over the last four or five weeks."
"He's got such a great personality, he's a very intelligent boy with a wonderful family, and we knew he would pick things up quickly. He did a lot of work with the goalkeeping coach, and we've seen him progress very, very quickly. It's great to see," he added.
Whether you think Krul is better than Forster or not, Newcastle will surely be ruing their decision to sell Forster for just £2m, whilst many will no doubt believe that he should have been kept regardless of the fee. Now, Magpies fans have to watch on as Forster keeps clean sheet after clean sheet whilst the Newcastle defence continues to leak goals.
