On that note, here are the Chelsea player ratings in the game:Kepa Arrizabalaga - 5/10He made one important save from Azmoun when Zenit were tearing Chelsea apart at the back. But he had no chance with any of their goals.Cesar Azpilicueta - 6.5/10Arguably the most consistent Chelsea defender on the night, the captain made four clearances and interceptions apiece.Andreas Christensen - 6/10He made some key blocks in the game, but at the same time looked completely lost during all of Zenit's goals. The Dane bagged an assist for Werner's opening goal with a wonderful flick-on, though.Malang Sarr - 7/10He went hard on Azmoun a few times, but made one nice block in the first period to thwart a counter attempt. Sarr made six clearances on the night.Callum Hudson-Odoi - 7/10He was a big threat with his movements, although he took too long on the ball in one crucial moment. Hudson-Odoi went into the books in the first half, prompting manager Tuchel to take him off early.Reece James - 6.5/10It was not his best night, but James wasn't too bad either. He provided a great cover for the back four, and distributed the ball excellently.Ross Barkley - 7.5/10A force to be reckoned with, Barkley was a lively attacking presence for Chelsea. He took one excellent shot from range that was caught by the Zenit keeper. Barkley also helped Werner following a neat one-two.Saul Niguez - 6.5/10It was his best performance in a Chelsea shirt yet. Niguez made defensive contributions, and also posed an offensive threat. However, none of his crosses on the night were accurate.Mason Mount - 6.5/10It was a disappointing night for Chelsea's golden boy, who couldn't have the same influence he's had in the league.Romelu Lukaku - 7.5/10A silent figure for much of the game, Lukaku took his chance and scored an Chelsea's equaliser to make it 2-2 on the night.ESPN UK@ESPNUKRomelu Lukaku scores his first goal for Chelsea in 3 months! 💥12:45 PM · Dec 9, 2021110452Romelu Lukaku scores his first goal for Chelsea in 3 months! 💥 https://t.co/r3t3jp2jqETimo Werner - 8.5/10After struggling for goals all season, the German striker bagged two on the night.
