The 28-year-old defender played a vital role in guiding the Blues to their second Champions League title last season.Rudiger is also one of the key men in Chelsea's outstanding start to the Premier League season. The Blues currently sit at the top of the standings.However, Rudiger has entered the final year of his contract. He has not come anywhere close to penning a new deal despite the Blues wanting to keep hold of their star defender.If Rudiger fails to sign a contract before January, the German international will be in a position to sign a pre-contract with a host of European clubs. The likes of Real Madrid, Bayern Munich and Paris Saint-Germain have all shown interest in signing the 28-year-old defender on a free transfer.Chelsea signing Attila Szalai could also act as a potential replacement for Thiago Silva. The former Paris Saint-Germain defender is 37 years old and will need replacing sooner rather than later.Chelsea have one of the best defense in the Premier LeagueChelsea have made an excellent start to the 2021-22 season and have their strong defense to thank. Thomas Tuchel usually plays a back three system with two wing-backs on either side.The likes of Antonio Rudiger, Thiago Silva and Andreas Christensen have been rock solid at the back. This helps the attackers create chances and score all the goals.As things stand, Chelsea have conceded only four goals in the Premier League, the lowest in the division. While the centre-backs continue to keep out the goals, the wing-backs remain a major goal threat going forward.Both Reece James and Ben Chilwell have been amongst the goals lately. Reece James has scored four goals across all competitions while Ben Chilwell has netted thrice.LDN@LDNFootbalIChilwell x James… 💫The best full-back pairing on the planet.1:54 AM · Nov 9, 20214341253Chilwell x James… 💫The best full-back pairing on the planet. https://t.co/sTx5OAtzkl
