Manchester United target Jadon Sancho is the world's most valuable young footballer, according to an expert report. The English winger, currently playing for Borussia Dortmund in Germany, is expected to move to the Premier League in the summer, with United leading the chase for the 20-year-old. But the Old Trafford club will certainly have to dig deep if they want to secure his signature. The <a href="https://football-observatory.com/">CIES Football Observatory </a>has calculated that Sancho's top value is an estimated £175m (Dh790m). CIES have valued the big five league footballers born in or after the year 2000. And according to their algorithm, Sancho's teammate Erling Haaland, is the second most valuable player at £89m. Norwegian striker Haaland has continued his prolific scoring form since joining from Salzburg, netting a remarkable 40 goals in 33 games this season. With four players, England are the most represented nation in the top 10 with Sancho, Callum Hudson-Odoi, Mason Greenwood and Phil Foden. French midfielder Eduardo Camavinga of Stade Rennais, aged 17, is the youngest player in the top 10. The photo gallery above lists the top-20 most valuable young footballers, in order from 1-20.
