Chelsea continued a recent slump under Graham Potter, falling well short of their best in an unambitious and disorganised showing against Arsenal at Stamford Bridge.
If Potter's 4-1 loss to former side Brighton was embarrassing, then being humbled at his new home ground by a side that finished below the Blues last season was worse. Chelsea register one - extremely tame and weak - shot on target and rarely looked like hitting anything approaching full stride or fluidity.
Meanwhile the slick Gunners cut Chelsea apart and dominated proceedings from start to finish and gave a stark contrast to the place Potter's team are in. Mikel Arteta has been given three years to gel his side and the Emirates' faithful are finally seeing rewards.
