Chelsea have exceeded the expectations of many this season. Following the instability that the club faced last term, many predicted that they would struggle to achieve a top-four finish this season, which would undoubtedly result in them losing key man Eden Hazard next summer.

However, the Blues have proven their doubters wrong – at least thus far. They have adapted well to life under new boss Maurizio Sarri and are currently the only team from Europe’s top five leagues that are unbeaten in all competitions.

While Sarri’s charges have been impressive, they have not been as lethal in front of goal as their Premier League counterparts Liverpool and Manchester City, and that is exactly why they languish in third place behind the duo, who were the pre-season favourites to contest this season’s challenge.

One man the Blues should consider signing in January if they want to boost their title chances is Bournemouth’s Callum Wilson. While the Blues are strong in almost every department, their weak point is their strike force. Olivier Giroud and Alvaro Morata have shown signs of brilliance so far, but the two do have a tendency to be rather inconsistent.

Wilson has been excellent so far this term, managing to contribute six goals and four assists for the Cherries. His form has also managed to win him a call-up to England for the upcoming friendly international against the United States.

The English international Wilson is pacy and also has better aerial ability than Giroud and Morata. At 26, he is approaching the peak of his career and now could be the right time to buy him.

It is hard to see Wilson not being keen on a move to Stamford Bridge, but Eddie Howe and Bournemouth may be naturally hesitant to sell one of their key men in January. The Blues, could, however, boost their chances of landing the player by offering someone like Gary Cahill as part of the deal. The veteran has been a fringe player for the Blues this season and it is quite evident that he has no future at Stamford Bridge.

However, Cahill still does have a lot to offer at the highest level and he could be a good asset to a club such as Bournemouth due to his experience. In addition to this, the Cherries could also lose the sensational Nathan Ake at the end of the season, so Cahill could be tempting for them as he could serve as a replacement for the youngster.
