The winter transfer window does not open until January 1, but clubs across Europe are busy planning and tentative negotiations will have begun in preparation.

Our friends at Football Whispers have scoured the European newspapers and websites to bring you the latest transfer gossip and news from the continent.

France

If David Luiz finalises a January move to Real Madrid, Chelsea manager Antonio Conte wants to bring Alex Sandro to Stamford Bridge. Having failed in the summer to convince Juventus to part with their left wing-back, Conte believes a big offer in January would be enough to make it happen. (Le10Sport).

Neymar's father has refused to close the door on his son sensationally joining Real Madrid in the future. When asked about the interest from the Spanish and European champions, he said: "Today we do not think of a departure and respond to this kind of thing, it would fuel something impossible. I cannot talk about negotiations that could take place in five or six years." (L'Equipe)

Spain

Neymar's record-breaking move to Paris Saint-Germain in the summer inadvertently cost Barcelona millions during contract negotiations with Lionel Messi. The club legend has put pen to paper on a new deal, but it is one they renegotiated after the Brazilian left the Nou Camp for Paris. Club officials in Catalonia didn't feel Messi's €300m (£266m) release clause was enough and upped it to €700m (£626m). Messi agreed to it but only after the current La Liga toppers increased his salary too. (Marca)

Barcelona remain interested in Mesut Ozil. The Arsenal playmaker is free to negotiate with foreign clubs in January with his contract coming to an end in July. However, there may now be a conflict of interest meaning Barcelona cannot make their move. The Gunners are on the verge of capturing Raul Sanllehi as their new director of football, with the Spaniard leaving behind his current role at the Camp Nou. Questions would be asked if he sold Ozil during the January window, even if it does make financial sense. (Marca)

Keylor Navas returned to the Real Madrid starting XI for the first time in a month last night. He started in a Copa del Rey match against third-tier side Fuenlabrada as Zinedine Zidane looked to get his No 1 up to speed. However, the Costa Rican had a night to forget after a shot he parried went in off the underside of the crossbar during a 2-2 draw. (AS)

Germany

In an attempt to keep Barcelona, Arsenal and Liverpool target Leon Goretzka at the club, Schalke are offering the midfielder a club-record deal which would see him pocket well over €100,000-per-week. (Bild)

FC Augsburg president Klaus Hofmann believes RB Leipzig do not have the correct license to be a Bundesliga club. He revealed this during the annual general meeting, saying: "I believe that Leipzig does not meet the factual requirements of a club within the framework of the rules of the DFB." (Kicker)

Hamburg's striking sensation Jann-Fiete Arp has emerged as a target for Chelsea. The 17-year-old has really caught the eye this season and netted on his full debut for the club. Markus Gisdol, his club coach, has refuted these links though, describing them as "fairytales". (Kicker)

Italy

Inter Milan are planning to offer striker Mauro Icardi a new deal this season. The Argentina international is being courted by the likes of Real Madrid, Paris Saint-Germain and Bayern Munich, but is in no hurry to leave the San Siro. Inter want to tie their captain down and increase the clause in his contract, but the feeling is negotiations will be quick due to the fact the player is in love with the club.

Former Manchester United and Newcastle United striker Giuseppe Rossi is returning to Serie A. The Italy international used his Twitter account to reveal he would be heading back to the Italian league, with Genoa expected to be his likely destination. (Calciomercato)

Former AC Milan forward Simone Verdi is on the radar of Inter Milan. The 25-year-old striker is viewed as the man to bolster Luciano Spalletti's attacking options as the club compete with Napoli and Juventus for the Scudetto. (Tuttosport)
