Bookies make it a 60% chance the attacker swaps the Westfalenstadion for West London.
Christian Pulisic is now odds-on to make a sensational move to Stamford Bridge in the January transfer window.
Bookmakers have slashed the American wonderkid's odds into 4/6, implying they believe there is a 60% chance he joins up with Maurizio Sarri at Chelsea.
His current club Borussia Dortmund have drifted out to 11/10 to keep hold of the 20-year-old, meaning that bookies think he is more likely to move than still be in Germany come February.
Dortmund have become somewhat of a selling club in recent years. They secured an astronomical fee for Ousmane Dembele, and with Jadon Sancho now in the ranks, Christian Pulisic could be the next youngster they offload for a hefty sum.
At Chelsea the signing of Pulisic may be significant, as he could be the man they see filling the boots of talisman Eden Hazard, The Belgium captain has made no secret of his desire to play for Real Madrid, and he is 8/1 to join the Champions League winners in January.
Oddschecker spokesman, George Elek: 'Pulisic was the the only ray of light in the below par USA team that took on England last week, and his availability would have most top clubs take note.
'A move to Chelsea wouldn't be his first foray into English football though; the American spent some time as a youth team player at Brackley Town.'
