Saturday's Premier League action gets underway with an all-London match-up between West Ham United and Chelsea at the London Stadium.
West Ham United fought back from an early deficit to hold high-flying Newcastle United to a 1-1 draw at St James' Park last weekend as Lucas Paqueta canceled out Callum Wilson's third-minute opener.
Under-fire David Moyes remains under heavy scrutiny despite dispatching Everton 2-0 in his Premier League home fixture, with the Hammers starting this round a mere one point clear of 18th-placed Toffees.
Although Moyes' men have picked up four points in their last two league outings (W1, D1), as many as they had in their previous nine (W1, D1, L7), they're still embroiled in a scary relegation scrap.
That must be music to Chelsea's ears as the visitors come into proceedings seeking a first Premier League triumph since a 1-0 beating of Crystal Palace in mid-January.
Graham Potter's men have since strung together back-to-back 'nil-nil' draws against Liverpool and Fulham, casting doubt on the ex-Brighton manager's long-term future in West London.
In spite of Chelsea's January splurge of over £300m, the Pensioners are virtually out of the top-four race, entering this round a whopping ten points off fourth-placed Newcastle United.
West Ham United
West Ham's last seven home encounters against Chelsea in the Premier League have fluctuated between winning (4) and not winning (D1, L2).
However, the Hammers have suffered a staggering eight defeats in their last ten London derbies in England's top-flight (W1, D1).
On a more positive note, the abovementioned triumph against Everton halted West Ham's frustrating run of three consecutive home league losses.
Unlike their hosts, Chelsea have often flourished in top-flight matches against cross-town rivals and could become the first club to hit a 150-win landmark in the Premier League London derbies come Saturday.
While their recent rough patch cannot inspire much confidence, the Blues can draw inspiration from having won four of their last five league games against West Ham (L1).
The continuation of that run would help Potter's side avoid going three successive Premier League fixtures without scoring, a feat they last endured in 2017.
