Mourinho with the strong arm of discipline, as Costa still remains benched, but Courtois gets to keep again.
Courtois has been out for three months now with a knee injury, but upon regaining fitness, has been called back into the first XI.
And Costa still has the bench to warm, after he was sat on it against Tottenham last weekend, following his actions against Mourinho.
Chelsea XI: Courtois; Ivanovic, Zouma, Cahill, Baba; Fabregas, Matic; Willian, Oscar, Pedro; Hazard.
Bournemouth XI: Boruc, Daniels, Cook, Francis, Smith, Arter, Gosling, Surman, Ritchie, Stanislas, King.
