Antonio Conte pointed to the impact of Michy Batshuayi and Cesc Fabregas as the duo helped inspire Chelsea to a comeback win over Watford.
The Blues maintained their perfect start to the new Premier League campaign by making it two wins out of two at Vicarage Road.
However, they were made to work for the three points and had to dig deep to overturn a one-goal deficit as Batshuayi and Diego Costa strikes turned the tables on the Hornets.
Batshuayi is knocking on the door for his first start after an assist and a goal in his two substitute appearances for the Blues so far.
Fabregas injected much-needed creativity into what was a compact midfield in the first half, leaving new head coach Conte grateful to have such firepower waiting in the wings.
“I’m pleased for the substitutes that came off the bench,” Conte told BBC Sport. “They showed great attitude and commitment with Cesc Fabregas and Michy Batshuayi making a real impact.
"We all know Cesc’s quality, he’s a great player but it’s important to understand that we are at the beginning of the season and I am looking for the right balance. I feel good because I saw the right commitment, the right spirit from my team.
"This game wasn’t easy this game because we were 1-0 down. I’m pleased to see the reaction from my players and this win is very important for us as it gives everyone confidence.
"It is wrong to come to Watford and to think it’s very simple to win. In the first half I saw a good balance between the teams. I think we showed a great intensity in the second half and we pushed them a lot.
"I like to thank the fans because they pushed us on during the worst period. We must understand that we have to fight together and today is another game that we won at the end so it’s very important."
Conte confirmed he remains in discussions with Chelsea transfer chiefs in an effort to add more depth to the Chelsea squad.
However, the Blues have been dealt a blow in their hunt for a new striker with the news this evening that Romelu Lukaku is staying at Everton.
The Belgian has informed manager Ronald Koeman of his intention to remain at Goodison Park for at least one more season.
