The Blues are currently three points above Manchester City at the top of the table. They also have a favorable set of fixtures in the coming weeks.They are expected to win against United and then have away games against the likes of Watford and West Ham United. While neither team is expected to roll over easily, Chelsea under Tuchel this season looks like the team to beat. The European Champions have had their fair share of injuries but have looked impressive both in defense and attack.B/R Football@brfootballChelsea confirm Ben Chilwell has a partial ACL injury and the club will decide whether he needs surgery in six weeks.N'Golo Kante will also miss this weekend's Manchester United game with a twisted knee.7:16 AM · Nov 26, 2021177131622Chelsea confirm Ben Chilwell has a partial ACL injury and the club will decide whether he needs surgery in six weeks.N'Golo Kante will also miss this weekend's Manchester United game with a twisted knee. https://t.co/t1dZZHVIXCThey have scored 30 Premier League goals in 12 matches so far while conceding just four. They have yet to concede more than one goal in a single game this season. Reece James is the team’s topscorer across all competitions with five goals. Tuchel’ system demands the fullbacks become an integral part of the team’s attacking plan. Hence, Ben Chilwell has also scored three Premier League goals thus far.Chilwell is out for six weeks due to a partial ACL injury. But both Marcus Alonso and Cesar Azpilicueta are more than capable of doing the job at the left wing-back position. Chelsea have recently welcomed the likes of Romelu Lukaku, Timo Werner and now Kai Havertz back from injury. Therefore the next few weeks can be expected to be even better.
