It's no secret that Chelsea need a striker.
They hoped that Alvaro Morata would be the answer to their problems last year.
However, Morata has had a turbulent spell at the club since signing for £60 million in 2017.
He started off well but, after numerous injury problems, he's struggled while on the pitch.
The 26-year-old scored 15 times in his debut campaign with Chelsea and has followed that up with just nine goals so far this term.
His struggles have lead to reports suggesting he wants to leave Chelsea, with AC Milan and Sevilla among the clubs interested in his services.
Other than Morata, Chelsea also have Olivier Giroud, but he does not provide the goals needed for Chelsea to be Premier League title contenders.
As a result of these problems, Maurizio Sarri has been playing Eden Hazard as a false-9.
But, that is likely to only be a temporary solution.
It has been believed that Chelsea have entered the transfer market this month to try and bolster their options up front.
One such name they have targeted is Callum Wilson.
However, Chelsea will likely have to stump off a considerable amount to prise Wilson away from Bournemouth.
And Dean Jones, journalist for Bleacher Report, has revealed just how much Chelsea will have to pay Bournemouth for his services.
Taking to Twitter, he wrote: "Was suggested to me today that if Chelsea want Callum Wilson they'll have to pay upwards of £50m... Possibly even up to £70m!"
That is just ridiculous.
No disrespect to Wilson - he has been very good this season - but to think Chelsea need to pay £70 million to buy him is extraordinary.
The last time Wilson scored over 10 goals in a season was in the 2014/15 campaign; when Bournemouth were in the Championship.
He has only managed 27 Premier League goals during his four seasons in the league.
The 26-year-old also has only one England appearance to his name.
And he is also plagued with injury concerns, having ruptured his anterior cruciate ligament in both knees.
So how does all that justify £70 million player?
The prices of players have gone up astronomically in recent years. Cristiano Ronaldo, the best player in 2008, went for £80 million.
Even that fee is a ridiculous amount of money.
Just over ten years on and a player with one England cap is valued 'just' £10 million less.
It shows just how crazy football transfer fees have become and many expressed their astonishment on Twitter.
