The Blues have been beaten in six of their last seven matches in all competitions during a disastrous run, failing to win in the process, with their last victory coming away to Leicester City on March 11.
Chelsea have seen their already-slim top-four hopes evaporate in recent weeks, with a total of 39 points from 32 matches leaving them down in 11th position in the table, some 21 points behind fourth-placed Manchester United.
Here, Sports Mole rounds up Chelsea's latest injury and suspension news ahead of their clash with Arsenal, who remain top of the table despite their damaging loss to Manchester City last weekend.
