Gittens, who is 20 years old, is considered one of the rising talents in the Bundesliga and has previously played in the academies of Chelsea and Manchester City before making a name for himself at Dortmund.

Chelsea faces stiff competition from Newcastle, which has entered the race strongly, with the player's future likely to be determined based on the results of the battle for Champions League qualification in the final round of the Premier League.

It is expected that the qualification of either team for the Champions League will tilt the scales in favor of securing the young player's signature.

Chelsea is looking to strengthen its squad with new attacking players after a series of unsuccessful signings in recent seasons, hoping that Gittens will be a strong technical addition to support its long-term project.
