One of Frank Lampard's best moments as Chelsea manager first time round came at the Emirates Stadium. One of his lowest points also came at the ground one year later in 2020.
As he heads back to north London with the Blues yet again there isn't load of hope that a positive outcome is within reach. His side haven't won in eight games - a run that has included games against Everton and Wolves - and are staring six straight losses down the barrel.
It's not the way he wanted to return and now, for the first time in nearly two decades, Chelsea are far from favourites as they journey up London on Tuesday night. When Lampard won there in 2019 it was an even contest, they went there comfortably in the top four 12 months later.
