As the Premier League season moves into its fourth month, it is becoming more clear as to where sides need strengthening.
Chelsea have had a pretty impressive start to the campaign, but there are areas of the pitch that have shown some cause for concern.
Having only one out and out striker has been the most publicised, but leaking goals has become a more apparent worry in the last few weeks.
So where will Chelsea look at strengthening in the January transfer window?
If the papers are to be believed, then a number of names have apparently been courted by the Blues, but which would be the biggest?
But for one reason or another, he chose to move to Madrid.
Since his move he has only improved and is now one of the most prolific goal scorers on the planet.
His form and skill have obviously now given him an inflated price tag, and the Daily Mail claims there may be a £46 million offer coming.
Money is not usually an issue for Chelsea, and if they want to spend the money for Falcao, they will, but will face stiff competition for his signature in the form of Real Madrid.
If Chelsea do manage to bring Falcao to the Premier League, then they will have bought a potential league-winning player.
If he can bring his La Liga form to England, then God help the defenders who have to face him.
Etienne Capoue to Chelsea is not the most prominent of rumours on the back pages of newspapers, but this may be due to the fact that not many people know how good this player really is.
If Chelsea wanted to highjack this deal, they have the spending power and allure to bring him to Stamford Bridge.
And why would they want to do that? To put it quite simply—he is a midfield general.
The two in Chelsea's 4-2-3-1 has come under question since the Blues have been leaking goals, and some fans wonder if the back four is getting enough protection.
In previous seasons, the finger would have been pointed at John Obi Mikel but he has improved greatly this season, so the problem probably lies somewhere else.
Oriol Romeu is still yet to show he is a top class player, and Roberto Di Matteo doesn't appear to be a fan of his so his playing time could remain at minimal.
Frank Lampard is getting older now and has been guilty of not following his defensive duties at times, which can leave the defence exposed.
This is why Capoue could be the perfect buy for Chelsea.
He is a ball winner who can break up play and tackle, and he has excellent distribution that could help turn defence in to attack and get the attacking midfielders more involved in the game quickly.
Yes, I am aware Lukaku is already a Chelsea player, but he is currently plying his trade on loan at West Bromwich Albion.
He has looked really sharp and powerful during his time with the Baggies, which has sparked talk of him returning from his loan spell early (via the Telegraph).
While Lukaku seems happy at West Brom, it is well-known that he is a Chelsea fan, and if he would be guaranteed playing time with the Blues, then Steve Clarke will have a hard job keeping hold of him.
With Fernando Torres' form once again coming under scrutiny, this could be the perfect time for Lukaku to come back and prove he is Chelsea's main man.
