The Blues are looking to revitalise their wings with transfer speculation surrounding Hazard and Willian. The Belgian superstar has been linked with a move to Real Madrid. Whilst Jose Mourinho wants a reunion with Willian, who he worked with during his second spell at Chelsea.
And it has led to the Stamford Bridge outfit looking at replacements, with Dortmund star Pulisic topping the list.
The American has a vastly growing reputation in the game and has the potential to become world-class.
The 27-year-old has been one of the top performers in the Premier League since his move in 2012.
He has helped the Blues win two Premier Leagues, the FA Cup, a League Cup and the Europa League.
But he recently hinted that he wants a move to the Bernabeu this summer.
