Daniel James has enjoyed an extremely positive start to life at Manchester United.
And that has already been reflected in the Welshman's transfer value.
The experts at Football Observatory have developed an algorithm to work out the worth of individual players.
It is a complex process explained in depth on their website here and is dependant on, among others factors, age, position, length of contract and the economic level of the holding club.
James moved to Old Trafford earlier this summer in a deal worth £18million, dependant on add-ons. An initial £15million was paid to Swansea City for the young Welshman, whose stunning rise to prominence last season saw him linked with several big-name clubs.
Liverpool, Arsenal, Tottenham and Manchester City were all said to be monitoring his situation, while long-time admirers Leeds United were frustrated in their attempts to sign him last January.
Now, according to the website , James is worth between €40million and €50million - more than doubling his original transfer fee.
He is contracted to United until the summer of 2025.
To place this is context, here are the values of other high-profile players in European football:
Kylian Mbappe - €250million
Raheem Sterling - €200million-€250million
Lionel Messi - €150million-€200million
Harry Kane - €150million-€200million
Paul Pogba - €90million-€120million
Cristiano Ronaldo - €90million-€120million
Neymar - €90million-€120million
Sergio Aguero - €70million-€90million
Gareth Bale - €30million-€40million
James came off the bench on his first Premier League start for United in their 4-0 win over Chelsea on the opening day of the season, scoring the fourth goal for Ole Gunnar Solskjaer's men.
He is in contention to feature for the Red Devils at Wolves this evening.
