#1 Jadon Sancho
Jadon Sancho has excelled since joining Borussia Dortmund, becoming the youngest-ever player to score eight goals in a single Bundesliga season. In doing so he has garnered the attention of a host of Europe's top clubs.
As well as an eye for goal, Sancho is an elite playmaker, racking up 9 goals and 9 assists in the Bundesliga already this season.
His combination of trickery and playmaking makes him ideal for a Chelsea side with an ageing Willian and Pedro. Both Willian and Pedro could leave the club at the end of the season as their contract with Chelsea expires.
The fact that Sancho can play on either flank or even possibly as a No. 10, makes him a versatile player for the Blues.
With tweets from his childhood surfacing that allude to the fact that he supports Chelsea, and his close friendship with Chelsea player Callum Hudson-Odoi, Chelsea might have a unique advantage when fighting for his signature.
