Chelsea retained capital bragging rights with a fourth-consecutive victory over London rivals Tottenham on Thursday evening, as Fernandez headed in Palmer's pinpoint cross to net the only goal of the game.
With Palmer returning to the side after missing the trip to Arsenal before the international break, and getting straight back into things with his eighth Premier League assist of the season, to tee up Fernandez's sixth goal of the campaign, Maresca was pleased with both players' contribution, even if he doesn't want the side to become too reliant one our No20.
'Tonight the assist for Enzo was a top assist,' said our head coach. 'Enzo was in the right position, so I am very happy for both of them.
'Cole Palmer’s performance tonight was very similar to the rest of his performances, the only difference is that in the previous performance he didn’t score or assist. Because he’s a top player, and probably the best player we have, every time he doesn’t score or assist it is news.
'But for me it is something normal. We cannot rely on Cole to score or assist in every game.'
He also felt the performance of the team as a whole was very positive. Even when we were diverted from our preferred possession-based style of play to dig deep and hold our lead during 12 minutes of added time at the end of the game, the Italian feels that kind of experience can only strengthen us as a group.
'Tonight was very important, first of all because of the performance. We know how important it is in this moment to win games, but since we started we try to win games in the way we want and I think tonight the performance as very good and we are happy.
'Probably since day one we don’t work every day to win the game in the way that we played in the last 10 minutes, in terms of waiting for them and giving the ball to them. But if you want to become a team I think you need to also learn to play how we played in the last 10 minutes, to win a game in a dirty way.
'I think for 90 minutes, until the added time, we were in control, we created enough chances to win the game. We created enough chances in the first half.
'To be honest that might have been my mistake because I made a change before I saw the added time and, when I saw it was 12 minutes, I thought it was probably too early to make that kind of change. Fortunately we won the game and we are happy.'
Finally, Maresca had a special message to the Chelsea fans inside Stamford Bridge on Thursday, thanking them for the fantastic atmosphere they created and the relentless backing they gave the Blues players throughout.
'I want to say that my feeling from the bench tonight was that we have the best environment with the fans since the start of the season,' he added. 'I was very happy with the way the fans were tonight.
'With them in the way they were tonight we are going to achieve important things, because they push us and they help us. So I’m very happy and, please, if they can do the same until the end it is good for us.'
