Some big names could be on the move in the coming few months, and we're here to keep you posted on the latest transfer rumours.
With that, here are the top transfer rumours of the day.
Four clubs in talks in Rudiger
Real Madrid, Paris Saint-Germain, Bayern Munich, and Juventus have all reportedly begun contract talks with Antonio Rudiger, according to Sky Sports.
Rudiger is set to leave Chelsea at the end of the current season and is free to negotiate a pre-contract with other teams.
Klopp wants Hazard
Jurgen Klopp reportedly wants to bring Eden Hazard to Liverpool this month as a backup for Mohamed Salah and Sadio Mane.
According to Spanish outlet El Nacional, Klopp wants to bring in a cover for the duo, and has suggested a potential loan move for the Real Madrid man. However, the Liverpool board do not seem keen on the former Chelsea man, and are reluctant to sanction a transfer.
Arsenal make Vlahovic bid
Arsenal have reportedly made an offer for Fiorentina striker Dusan Vlahovic that is worth €70m, according to Gazzette dello Sport.
Mikel Arteta is keen to shore up his attacking options with Pierre Emerick-Aubameyang fallen out of favour and Alexandre Lacazette's contract expiring at the end of the current season. The Gunners are willing to pay £46m to bring the highly-rated Serb to the Premier League.
