Chelsea's signing of £97.5m striker Romelu Lukaku in the summer was supposed to be the final piece in the Blues' title-winning jigsaw.
But Lukaku has struggled to make the expected impact, scoring five goals in an injury-affected season, and Thomas Tuchel's side now find themselves 10 points adrift of leaders Manchester City, having played a game more.
The Belgian is still the club's highest-scoring forward this season but they do have another attacker on their books who has hit the back of the net as often as Lukaku.
Instead of impressing at Stamford Bridge, however, he is catching the eye on the south coast.
