Frank Lampard has lost his job as Chelsea boss after a run of five defeats from eight Premier League games.

Here, the PA news agency looks at five key results that led to his departure.

Chelsea 1 Manchester City 3, Sunday, January 3, 2021

Chelsea v Manchester City – Premier League – Stamford Bridge
Frank Lampard looks exasperated on the touchline during the 3-1 Premier League defeat against Manchester City at Stamford Bridge.

The major catalyst for Lampard’s departure. City were 3-0 up just past the half-hour and could have had five in the first-half alone. Chelsea were worryingly off the pace in 45 minutes where untold damage was done – not just in terms of the result on the day, but also to Lampard’s tenure.

Arsenal 3 Chelsea 1, Saturday, December 26, 2020

Arsenal v Chelsea – Premier League – Emirates Stadium
Chelsea’s Tammy Abraham appears dejected at the end of a 3-1 Boxing Day defeat against struggling Arsenal at the Emirates Stadium..

Chelsea arrived at the Emirates Stadium to face an Arsenal side in crisis, only to leave as the London club with the bigger problems. Mikel Arteta spent the build-up insisting Arsenal only had a week to save themselves from a relegation battle, so bleak was their Boxing Day plight. But this was to be the day that Arsenal’s fortunes changed, as Alexandre Lacazette, Granit Xhaka and Bukayo Saka condemned Chelsea to a hefty London derby defeat. Tammy Abraham’s late consolation did nothing to ease the frustrations and growing unease for the west Londoners.

Everton 1 Chelsea 0, December 12, 2020

Everton v Chelsea – Premier League – Goodison Park
Everton’s Gylfi Sigurdsson fires home the penalty to condemn Chelsea to a 1-0 defeat at Goodison Park in December.

Gylfi Sigurdsson’s penalty proved enough for Carlo Ancelotti to get one over on his former Chelsea charge Lampard. Chelsea dominated possession but could do precious little with it, and that lack of cutting edge despite all the talents on display underpinned Lampard’s eventual downfall.

Wolves 2 Chelsea 1, December 15, 2020

Wolverhampton Wanderers v Chelsea – Premier League – Molineux
Thiago Silva (centre) in despair after Pedro Neto’s last-gasp winner for Wolves in a game where Chelsea took the lead but could not hold it.

Olivier Giroud’s goal had Chelsea in front in the second-half and looking at keeping a clean sheet to tiptoe out of Molineux with what would have been a fine result. Even when Daniel Podence equalised just past the hour, Lampard would have expected his side to hit back and conjure a winner. Instead it was the hosts who did just that, with Pedro Neto’s last-gasp effort flooring the visitors.

Bayern Munich 4 Chelsea 1, August 8, 2020

Bayern Munich v Chelsea – UEFA Champions League – Round of 16 – Second Leg – Allianz Arena
Frank Lampard looks stern-faced after a 4-1 Champions League defeat against Bayern Munich at the Allianz Arena in August.

That Bayern moved on from this last-16 drubbing to lift the Champions League title eased Chelsea’s great pain not one jot. The aggregate 7-1 scoreline stung. This defeat and its manner doubtless helped Lampard convince Chelsea’s board that reinforcements and plenty of them were required for the Blues to push back into Europe’s genuine elite.
