FA Cup - Kalou saves sluggish Chelsea
Substitute Salomon Kalou kept holders Chelsea in the FA Cup, earning them a 1-1 fourth round draw against Everton at Goodison Park.
The Ivorian struck on 75 minutes, completely against the run of play, to send the tie to a replay as Chelsea bid to win the competition for the third year in a row.
Louis Saha had put Everton in front just after the hour mark with a powerful header, his seventh goal in eight games against Chelsea.
Saha returned to the Everton starting XI, having proved Chelsea's tormentor on several prior occasions.
The Frenchman hit the fastest FA Cup final goal against them, scoring after 25 seconds at Wembley in 2009, although Chelsea won the match 2-1.
Saha also scored three times against Chelsea last season, including both goals in a 2-1 win at Goodison.
However, he often looked isolated up front in the absence of Tim Cahill - still on Asian Cup duty with Australia - especially with Mikel Arteta unusually quiet.
The teams' last FA Cup meeting had an explosive start, but this encounter took a long time to get going.
Diniyar Bilyaletdinov nearly caught Jose Bosingwa napping in the box, as he stole in front of the full-back on 12 minutes to meet a low cross, but his shot went wide. The Russian later had a glancing header saved after Branislav Ivanovic misjudged the fight of the ball.
Jack Rodwell had the best Everton chance of the first half, when he was played through by Saha after good work by Marouane Fellaini - but the midfielder hit is shot straight at Cech.
At the other end, Nicolas Anelka had a similar chance to Rodwell's, and the result was the same, as Tim Howard made a decent save.
Otherwise, Chelsea had to make do with scraps, such as the two corners headed over by John Terry and a wayward Michael Essien volley.
Everton added some much-needed spark after the break, as Saha had a volley blocked from a tight angle and Fellaini had a powerful header tipped over.
The breakthrough came on 62 minutes from an inswinging Leighton Baines corner. Saha leapt highest and powered his header past Cech from seven yards.
Everton should have put the game out of reach as they dominated proceedings.
On 74 minutes the lively Seamus Coleman met a Baines cross with a downward header that Cech pushed away, then Essien flew in with a superb block to prevent the Irishman converting the rebound.
Less than a minute later, Chelsea were level completely against the run of play. They came away on the break and Drogba found Kalou in space on the right. Kalou jinked past Sylvain Distin and rolled a diagonal shot inside the right corner.
The sense of deflation around Goodison was huge, and Chelsea might have nicked it late on.
Nicolas Anelka had a shot saved by Howard from another counter-attack, while Ramires struck a long-range shot against the post late on.
Sub Jermaine Beckford has Everton's best chance, seizing on a sliced Ivanovic clearance and seeing his powerful volley tipped over by Cech.
