#3 Christian Pulisic (Borussia Dortmund)
At the moment, this one looks the most likely deal to happen in January. There have been a number of reports that claim Chelsea are now at the front of the queue for Pulisic, and a deal could be done in January.
It is a position that the Blues may be looking to strengthen in January. Eden Hazard has been superb out on the left flank, but they have struggled for consistency on the opposite wing, with both Pedro and Willian both failing to hit top form.
There is a chance that Pulisic will be pushing for a move this summer, having fallen down the pecking order at Dortmund, with Marco Reus returning to full fitness, and Jadon Sancho proving a real revelation.
Because of this, the American has played just 379 minutes in the Bundesliga so far this season. He won’t be assured of a regular spot in the side at Chelsea, but he may be willing to take his chances in the Premier League.
