This past summer Jose Mourinho set his sights on Wayne Rooney, a proven goalscorer whose future was far from certain at Old Trafford.
However it wouldn't take Einstein to realise that David Moyes would not let Rooney leave, so Chelsea were quickly rebuffed and had to quickly move elsewhere before the transfer window slammed shut.
Mourinho moved for Samuel Eto'o, who has scored just four goals this season. Although the striker is a proven goalscorer and would bring valuable experience, the star does not stop ageing and his wage demands are inexcusable.
So perhaps there would have been better strikers to sign, such as Manchester City forward, Edin Dzeko.
Dzeko doesn't get enough opportunities at the Etihad, despite being a class act.
He currently sits fourth in the pecking order at the club, facing competition from the two new signings of Stevan Jovetic and Alvaro Negredo and the ever present Sergio Aguero who never seems to do anything wrong.
The Bosnian was dubbed 'super sub' however again he finds himself limited to cameo appearances which even he says are not enough to fulfil his needs.
Dzeko was City's top goalscorer last season with 14 goals from 32 games, and a bid of £25 million could have been enough to take Dzeko away from the City.
So why don't Chelsea move for the Bosnian?
With Torres not yet acquainted with the goal, Ba limited in his opportunity and Eto'o overpaid and overrated, it could be down signing Dzeko in order to save the Blues' season.
There is still the January transfer window to go, and hopefully for Blues fans, Dzeko will be on his way down to Stamford Bridge.
