Chelsea are eager to bring in attacking options in January, with Andy Carroll reportedly the most likely target for Antonio Conte's side.
However, Watford's Richarlison could also be targeted with the Blues apparently keen on the young Brazilian and have already spoken about summer deal.
Despite having the joint best defensive record in the league, Chelsea are lagging behind several of their direct rivals when it comes to goals scored, with their last three matches all resulting in goalless stalemates.
Consequently, the London side are keen to bolster their attacking prowess and ease the stress on the misfiring Alvaro Morata.
Becoming the club's most expensive ever signing in the summer, the Spaniard is enduring a goal drought, having failed to find the back of the net in five games and looks off the pace.
Goal report Chelsea wish to take Andy Carroll on loan for the remainder of the season, but West Ham will be hesitant to do so as Javier Hernandez and Diafra Sakho may be leaving.
While the Englishman would act as a temporary measure, plans for long-term targets are already being drawn up.
One of these is former player Thorgan Hazard - brother of Eden - who has established himself as a key player for Borussia Moenchengladbach in Germany, and has been linked with a return before.

Looking closer to home, Richarlison is also being touted as an ideal candidate, with Goal claiming the Watford hitman is not an option in January, but talks have been held with agent Giuliano Bertolucci - a representative of several Chelsea players.
The Brazilian has five goals and four assists in the Premier League and was instrumental to the Hornets' fine start.
The reigning champions are adamant Morata is still their first choice striker, but are willing to let Michy Batshuayi leave on loan.
The Belgian has made just two league starts and finds himself isolated from Conte's team picture, but is willing to leave to increase his World Cup chances, with Sevilla showing interest.
