Chelsea manager Antonio Conte was happy with the contribution of Michy Batshuayi, who scored a brace in Saturday’s win over Watford.
The Blues fell behind against the Hornets after Pedro’s super strike opened the scoring, but the Belgian’s 61st-minute introduction for Alvaro Morata and subsequent goals helped them to a 4-2 win at Stamford Bridge.
"When you play three games [in a week] and are using the same players it’s important to make important decisions," Conte said, with Chelsea have faced a Champions League match against Roma on Wednesday.
"Sometimes the decision works, sometimes it doesn’t, but today I was lucky. If you compare this season with last, Michy is now playing a lot.
"Against Crystal Palace (a 2-1 defeat) his performance was not good but it wasn’t only him. Today the impact was incredible, important, and we must continue this way."
The comeback against the Hornets, which also saw Cesar Azpilicueta find the net, avoided what would have been a third straight defeat for the reigning champions, but Conte said he was never fearing the sack.
"I feel a lot of pressure but not this type of pressure," he said. "If the club decides to sack me, honestly, I don’t feel this pressure.
"I trust in my work, I try to give everything for the club; I did this last season, I’m doing it this season and I will never be worried about this – never."
