England winger Jadon Sancho’s transfer value has risen by an astonishing 806% to £79.44m over the past three months, according to new analysis.

The figures, from CIES Football Observatory, show the 18-year-old ex-Manchester City player’s rapid rise.

Sancho, who made his senior England debut in October, joined Borussia Dortmund for about £10m in 2017 and was valued at £8.77m in September.

He has scored six times in 21 appearances for Dortmund this season.

Meanwhile, the value of Liverpool’s 24-year-old Scotland defender Andrew Robertson has risen by £28.92m to £72.12m, while Everton forward Richarlison, who joined the Toffees from Watford in July in a £50m deal, is now worth £68.96m.

The 21-year-old made his debut for Brazil in September and has scored three times in six international appearances.

Manchester United defender Luke Shaw, 23, is worth 237% more than three months ago, his revised value of £30.46m a reflection of his improved status at Old Trafford.

Watford striker Isaac Success, 22, and Bournemouth forward Callum Wilson are now estimated to be worth £10.66m and £30.37m respectively, 195% and 158% more than at the beginning of September.

Wilson, 26, scored on his England debut last month and has netted eight times in the Premier League this season.
