The Chelsea youth product will be looking to emulate the likes of Mason Mount and Tammy Abraham to cement his place in the starting XI.#4 Patrick Viera's Crystal Palace fail to impress against a dominant ChelseaChelsea v Crystal Palace - Premier LeagueCrystal Palace were definitely the underdogs in the fixture against European champions Chelsea but they failed to give a good account of themselves in the first competitive game under new manager Patrick Vieira.They could muster only one shot on target and spent the majority of the game chasing the ball. Vieira changed the formation from 4-4-2 to a 4-3-3, but they were dominated by the hosts in every part of the pitch.Patrick Vieira has now lost more Premier League matches against Chelsea as a manager (P1 L1) than he did during his playing career (P10 L0).It’s a different game in the dugout. pic.twitter.com/hVP7Wc8DLO— William Hill (@WilliamHill) August 14, 2021Their main player, Wilfred Zaha, was hardly involved in the buildup and the defenders were not comfortable in possession and became disorganized under pressure.This was their eighth straight defeat at the hands of Chelsea and it seems the team needs some time to adjust to Vieira's tactics.Also See: The 10 highest-paid goalkeepers in the world
