Chelsea accomplished a very convincing 4-0 win at Stoke City yesterday, and Morata said the result "sent a good message to all the Premier League", in a post entitled "In the Fight."
Morata (L) was, however, unable to find the net against arch-rivals Arsenal last week!
Leroy Sane opened the scoring after a sloppy start from the hosts, but after that, it was one-way traffic.
Morata's first three goals for the Blues came off his head, but it took him just two minutes to change that as he met Cesar Azpilicueta's through ball with a cool side-footed finish.
The Blues boss confirmed a huge injury boost with the news that Tiemoue Bakayoko is fit and available for selection despite being involved in a minor auto accident outside the clubs training ground yesterday.
Morata wasn't the only Spaniard to shine at Stoke, though.
While Chelsea may be in a bit of bother without David Luiz, Stoke are undoubtedly worse-off injury wise with their issues also coming at centre back.
Mexico city: a new quake of magnitude 6.1 has struck southern Mexico
Two women died of a heart attack in Mexico City after a seismic alert system was activated by the temblor, Efe news reported. The government's response to the disaster is under close scrutiny ahead of a presidential election next year.
On Saturday Conte's words were more prosaic but equally heartfelt.
It seemed nothing would go Stoke's way and Morata finished any thoughts of a comeback with 13 minutes remaining.
But it also means Morata is the undisputed No. 9 at Stamford Bridge and the club's success, or otherwise, will largely be down to how many goals he scores.
Chelsea had further chances to pile on the misery, as Morata fizzed one wide and failed to convert a simple chance from a couple of yards out.
At the Etihad Stadium, a brace from Raheem Sterling and goals from Leroy Sane, Sergio Aguero and Fabian Delph for Manchester City ensured a 5-0 thumping of Crystal Palace. The two teams match up next weekend in the first heavyweight bout of the season.
Chelsea return to Champions League action on Wednesday night when they travel to Spain to take on Costa's new club Atletico Madrid.
