The Friedkin Group, Everton’s American owners, will be risking the fury of their own fanbase should they agree to the sale of Harrison Armstrong to Nottingham Forest.

The notion that Everton could even consider parting with Armstrong sparked an instant reaction of disbelief and anger among supporters, with the teenager regarded as their brightest home-grown prospect for years and a big hope for the future.

As yet, there are no indications that Everton will accept an offer, but Forest’s interest is real, although it would be a real coup should they pull it off.

It would also send out worrying signals about the scale of TFG’s ambitions.

Manager David Moyes has been frustrated by the club’s lack of incoming transfer activity this summer.

Moyes made it abundantly clear after Wednesday’s 4-0 Carabao Cup second-round win at Championship side Preston that he wanted reinforcements.

His hope was that TFG would provide backing for further arrivals.

Since then, however, Everton’s main creator Iliman Ndiaye has been heavily linked with Manchester City, and now Forest are ready to test their resolve over Armstrong.

How Moyes would view, or indeed explain, such a sale, would be intriguing. It would appear totally at odds with his stated intention of building a better squad.

And while Everton and their support may have to accept their prize assets being spirited away by clubs such as Manchester City, the idea that their most promising young player could be taken away by Nottingham Forest – a club they would be expecting to challenge or even surpass – may be harder to stomach.

That is why the manner in which Everton handle Forest’s approach for Armstrong, who has already excelled this season, may be a defining moment for TFG and Moyes.
