The 53-year-old Spaniard guided the West London club to Premier League victories against Sunderland, Fulham and Swansea City and secured a 2-2 draw against his former club Liverpool at Anfield last month.
"Always when you can win a trophy it is good and when you win this kind of trophy it means that the staff and everyone involved is doing well," Benitez told the club's official website. "At this stage of the season it is really important when you are playing for something, so if we can carry on winning games I will be really pleased.
"It is important to understand that a manager can do good things but it depends on the people behind supporting you, so it is important to give credit to everyone.
"We have to give credit to the staff because we have had not had too many injuries and I was telling the players after saying well done for making the Europa League final that everybody has to feel they have been part of this, because when you use players for different games and still the team can keep the level it means the squad is important."
With four Premier League games remaining, Chelsea sits third in the table, one point ahead of Arsenal, which has played a game more, and remains on course to secure an automatic place in next season's Champions League.
Benitez, who has also guided the club to a Europa League final, believes the cohesion between his players is improving and insists the squad's mentality is a factor behind their recent form.
"When you are working with the same group of players every week the understanding between players, management and staff is better," Benitez said. "We have a group of players with quality and we have the commitment that we saw in some of the games.
"As soon as you can win some games in a row you have momentum and confidence and it is easier, so we are not doing too many things in a different way but we are more convinced that we can beat anyone. Overall it is a good period, the team has more confidence and that is the key.
"We were scoring set-piece goals, especially from corners, and we were not conceding many and it is a good balance when you have a team with players who are good in the air.
"Some things that we are trying to do in training sessions you could see make the difference in the games and we are really pleased with that."
