Brighton have lost just two home games this season to Liverpool and Manchester City.
The Blues sealed a rather unconvincing 2-0 win over Brighton last time around, and they face a tricky prospect on the road with a couple of injury and suspension concerns.
There was little that Ryan could do to stop Willian's 20-yard thunderbolt, but he did save well from the Brazilian, Batshuayi and Tiemoue Bakayoko as Chelsea cut open the Seagulls at will in the first half.
"Pedro's reaction was to stand up quickly (not to appeal for a penalty)".
While Conte may still sign a striker in this transfer window, bringing others into play and getting the best out of Hazard and Willian could have ensured Batshuayi's Chelsea career is given a new lease of life. Between just before Christmas and last weekend, Chelsea games were 0-0 at half-time against Everton, Brighton, Arsenal, Norwich, Arsenal again and Leicester. There were moments of struggle earlier that included Brighton being denied a stone wall penalty as Willy Caballero fouled Ezequiel Schelotto.
In 23 Premier League appearances so far Courtois has kept 12 clean sheets, only David de Gea (13) has kept more.
Conte, however, was tight-lipped ahead of a match against Brighton where Chelsea will look to maintain their grip on a top four place that will guarantee qualification for the Champions League.
The Seagulls were unable to play their new striker after missing the deadline to register him for the Chelsea clash - he is also now out with a hamstring injury.
Albion wing back Schelotto arguably was their busiest player on the pitch and came close to scoring on 66 minutes as he pounced on a loose ball to race into the box, but could only poke the ball into Caballero's path.
And the 28-year-old had a lot of success against the Spaniard, looking more eager to win the ball and forcing his opponent into making mistakes.
Chelsea had shrugged off their poor run of form in recent weeks to make the ideal start on the South Coast - with Hazard leading the charge with a man of the match performance.
