Premier League clubs are on alert as Norwich are prepared to sell starlet Max Aarons to fund a better top-flight assault.
The Canaries kept England U21 right-back Aarons,21, after relegation last year despite interest from Barcelona.
But the self-funding Norfolk club now want to invest more in new players and Aarons is arguably their biggest payday.
The full-back has had another stellar season playing 42 times for the promoted Championship leaders.
City have other in-demand assets like Emiliano Buendia, who is like by Arsenal, and Todd Cantwell.
But they hope sacrificing Aarons can generate at least £30million to plough into squad strengthening and already committed to buying Ben Gibson for £8.5m.
Norwich were relegated in bottom place last season after spending a fraction on new players as the club invested in their infrastructure instead.
They then raised £40m from selling Jamal Lewis and Ben Godfrey after going down.
Now their swish upgraded training ground means they can put the majority of any new funds into players instead.
Canaries sporting director Stuart Webber is a highly-rated talent spotter who has licence to wheel and deal.
Aarons has made 127 appearances for Norwich, scoring four goals, since his debut in 2018 and helped them win the Championship in 2019.
