Chelsea need an answer to their problems up front and quick.
The Blues have been heavily reliant on the goals of Eden Hazard all season under Maurizio Sarri, with both Olivier Giroud and Alvaro Morata failing to nail down a starting spot.
As such, Sarri has used Hazard as a 'false nine' for a number of games, an experiment that hasn't exactly worked.
The Belgian looked back to his best in the 2-1 win over Tottenham when deployed out on the left-hand side of a front three.
And it's a position he should return to for the remainder of the season, with Gonzalo Higuain brought in to occupy the central striking role of the team.
The Argentine had a difficult spell with AC Milan in the first-half of the campaign, mustering just five goals.
But it must be remembered that under Sarri at Napoli, Higuain scored an unprecedented 36 Serie A goals in just 35 games.
So is he the answer for Chelsea? Well, former player and manager Ruud Gullit is not convinced that Higuain is the solution for Sarri.
Gullit wrote for the BBC: "I hope I am wrong, I really do, but Higuain is an old-fashioned striker who needs crosses and, if he plays up front all the time, he will not see many balls there because of the way Eden Hazard and Willian play.
"Those two always come inside, and dribble or shoot, and try to do things themselves.
"So they don't need a player up there who is a target man, because Chelsea don't use one and, under Sarri, they never do.
"Instead they need a centre-forward who can play in midfield too, and be effective on the ball as well as be a finisher inside the box. Roberto Firmino, who comes so deep for Liverpool, is the perfect example.
"That is how Chelsea's front man has to play too, which is why I am not sure Higuain is the answer. At the very least, he has a difficult job because, with the way they are set-up, he will not be able to play the way he wants.
"We will have to wait and see, but Alvaro Morata and Olivier Giroud are both good strikers, and it has not worked out for them."
It's an opinion that will certainly divide opinion.
Do you think Higuain will be the answer for Chelsea, or do they need a striker in the mould of Liverpool's Roberto Firmino? Let us know in the comment box below.
