Jadon Sancho is "essential" for Borussia Dortmund, according to Marco Reus, who says "time will tell" if the Manchester United target can go onto become as great as Cristiano Ronaldo.
Sancho has become one of the most important members of Dortmund's squad since moving to Westfalenstadion from Manchester City in 2017.
The England international has recorded 35 goals and 45 assists across his first 101 outings for Lucien Favre's side, helping them challenge Bayern for supremacy in Germany while also making a mark in the Champions League.
