Barcelona have begun the 2017/18 campaign in incredible form despite a hugely disappointing summer in the transfer market.
Key forward Neymar was resentfully sold for a world record £198m after Paris Saint-Germain triggered his release clause.
Meanwhile, Barcelona failed to prize prime target Philippe Coutinho away from Liverpool, despite offering over £100m.
The Catalan giants did complete the £135m signing of Borussia Dortmund winger Ousmane Dembele - but he has already been ruled out with a long-term injury.
Spearheaded by Leo Messi, Barcelona boast an 100% record in all competitions since their embarrassing Spanish Super Cup final defeat to Real Madrid.
Messi has scored 11 La Liga goals in the opening seven games and Barca already have a five-point lead at the top of table.
Barca's January business
Spanish newspaper Marca have revealed the four pieces of business Barcelona will be looking to complete in the January transfer window.
A star signing
Coutinho is still top of Barcelona's wishlist and the club are hoping to bring him to the Camp Nou as soon as January.
"We are [financially] prepared to sign Coutinho or any other player in January," Barca CEO Oscar Grau said at a news conference on Wednesday.
The 25-year-old attacking midfielder handed in a transfer request at Anfield over the summer in a desperate bid to secure his dream move.
Barcelona have already agreed a €9m transfer for the 24-year-old Colombian but his arrival date has not yet been decided.
The Palmeiras central defender - who will provide competition for Gerard Pique and Samuel Umtiti - could move either in January or next summer.
PSG's Italian star Marco Verratti has long been on Barcelona's wishlist but the club may move for Schalke midfielder Leon Goretzka.
Likely to be available at a cut-price in the upcoming transfer window, Goretzka's contract expires next June and will be free to agree a contract with overseas clubs from January.
Jean Michael Seri came very close to becoming a Barca player until the plug was pulled on the deal at the last moment - he could yet be a January target too.
The former Atletico Madrid is yet to make an appearance this season despite Barcelona's lack of recognised attacking options.
Turan, 30, still has three years left on his current deal in Catalonia and the club will do their utmost to move him on in January.
Arsenal and Galatasaray are two clubs who have been linked.
