Second-half latest: Everton 0 Chelsea 0 – Costa goes close for Blues
Diego Costa went agonisingly close to giving Chelsea the lead in an increasingly open FA Cup quarter-final.
A cagey first half saw both sides struggle to create opportunities but, after Everton’s Ramiro Funes Mori went close with a second-half header, Costa was unlucky to see his effort roll across goal from a tight angle.
Chelsea grew in confidence after a slow start to a fiercely competitive tie at Goodison Park.
Everton played a high-tempo pressing game from the off, but Chelsea stayed solid defensively and refused to be rattled.
Tom Cleverley had a feeble shot easily saved by Thibaut Courtois inside a minute.
But the visitors slowly began to dominate possession and looked the more likely to score.
Kenedy shot over after a fine run and clever interchange of passes with Pedro, and Willian went close with a free-kick late in the half.
Costa, starting up front despite a hip injury which saw him come off in the Champions League defeat against Paris St-Germain, was booked early on following a tussle with Gareth Barry.
Eden Hazard was left out of the squad but captain John Terry was included on the bench following injury.
Subs: Howard, Stones, Niasse, Besic, Osman, Deulofeu, Kone.
Chelsea: Courtois; Azpilicueta, Cahill, Ivanovic, Kenedy; Mikel, Matic; Willian, Fabregas, Pedro; Costa.
Subs: Begovic, Baba, Terry, Loftus-Cheek, Oscar, Traore, Remy.
