Get excited football fans. The time is here. The time when your club has the opportunity to make a deal that could change their season.
It could be the difference between relegation and survival; between being champions and runners-up; between qualifying for the Champions League or Europa League.
And with the amount of rumours swirling around at this time of year, it can sometimes be difficult to decipher the truth.
Not to worry however, because here at Tribalfootball, we have broken down the week's hottest transfer rumours, and informed you whether to believe the paper talk or not.
Kylian Mbappe - PSG
Clubs Interested: Manchester United
Considering Manchester United's woes, Jose Mourinho is keen on introducing a new dynamic to the team's attack, and that might come in the form of French wonderkid Kylian Mbappe given the Portuguese tactician has made contact with the player's representatives.
PSG are expected to sign Mbappe on a permanent basis during the summer transfer window for a fee in the region of €180m, unless a team comes in with a much higher offer.
Jose Mourinho may be keen on acquiring Mbappe's services, but according to Spanish news outlet Don Balon, the Manchester United will not allow Mourinho to spend more than €250m for any single signing regardless of the player's status.
Likelihood: Depends on how much PSG are willing to pay in case of a counter-offer
Alex Sandro - Juventus
The Blues have been handed a massive transfer boost in their quest to sign Brazilian full-back Alex Sandro as Juventus are reportedly ready to let the 26-year-old go during the January transfer window.
According to Tuttosport, Chelsea will have to compete with rivals Manchester United and Manchester City for Sandro's signature, but unlike before, Juventus are now willing to lower their asking price for the player down to £60m even after rejecting bids of up to €70m last summer.
With a replacement in the form of Leonardo Spinazzola already lined up for Juve, they view no need to keep hold of Sandro when they could command a sizeable fee from his transfer in January.
Sandro's arrival would provide some competition for Marcos Alonso and, in turn, improve the quality of Chelsea's left wing-back position.
Likelihood: Let's wait and see
Julian Draxler - PSG
Clubs Interested: Arsenal
Another transfer window, another link with Draxler – this time for sure right?
Arsenal have reportedly contacted PSG over a possible move for Julian Draxler during the January transfer window, and the Paris based club have issued an asking price of £40m for the Germany international.
The deal, though, is subject to whether the Gunners are able to attract a similar fee for Chilean forward Alexis Sanchez during the January transfer window, although it is believed that should they fail to find a suitor for Sanchez in January, they will wait until the end of the season to sign Draxler.
Arsene Wenger views Draxler as the ideal replacement for wantaway Alexis Sanchez.
Likelihood: Unlikely given Manchester City will probably wait for Sanchez' contract to run out.
Clubs Interested: China, PSG
Fellaini, who not long ago finally developed into a fan-favourite at Old Trafford does not intend to extend his stay with the Red Devils according to the Sunday Express.
His search for a new team is already underway but a source close to the 30-year-old Belgian midfielder has revealed that he has an offer from a Chinese Super League club and could make a move to the Far East in search of a bigger pay check.
Fellaini's influence in United's midfield really shone through at the start of the season as he got on the end of attacks and used his physicality to dominate the middle of the park.
Likelihood: Looks like Fellaini will be off.
Despite his fine start to the season Henrikh Mlhitaryan appears to have fallen out with Jose Mourinho who has deemed the Armenian playmaker surplus to requirements.
The midfielder has been left out of Mourinho's plans for a while now despite playing an instrumental role in United's early season triumph.
United will reportedly demand a fee in the region of £35m for Mkhitaryan and Inter Milan appear to be ready to splash the cash.
Likelihood: Let's see how things pan out
