Frank Lampard singled out defensive additions Thiago Silva and Edouard Mendy for praise after Chelsea drew 0-0 with Sevilla in the Champions League.
The Blues' last outing saw them concede three times as Southampton snatched a draw at Stamford Bridge, but they looked a far more solid outfit en route to their first point in Group E on Tuesday evening.
Lampard had made three changes to his defence from Saturday, bringing in Reece James at right-back, Mendy in goal and Silva in the heart of the back four.
He reserved special praise for the latter pair, who he believes can have a major impact on Chelsea's defending after arriving during the transfer window.
"It's something you strive for always and I mentioned before about the personnel we had back in today," Lampard told reporters.
"Thiago I thought showed the things I've spoken about, experience and quality; Mendy has probably one good save to make and he makes it, was good with his feet.
"[It was] against a very good team, a very organised defensive performance. They give you a lot of threats, they're very good, that's why they've been so successful in the last year or two, so I was pleased with that side of it.
"We lost a goal in the last minutes at the weekend that loses us two points. When you've got that feeling fresh in your mind, it's really important that you get over it. To get through that game will give us confidence.
"We're going to get better, I keep saying the same thing, but we haven't had the personnel in there playing regularly, getting relationships, working off each other.
"The more we do that, then we'll get better naturally."
Lampard, who has experienced his first goalless draw as Chelsea boss in what was his 62nd match in charge, also hailed work done on the training ground as a key factor in largely keeping a potentially dangerous Sevilla side quiet across the 90 minutes.
He continued: "It's always both. The work is a constant and you analyse the opposition and the threats that they're going to give you. With Sevilla, it was crosses and getting balls in the box.
"They've got quality, they play really well throughout the team but you might expect a team from La Liga to come and try and play a lot of passes through the lines, but they get a lot of crosses in.
"We dealt with all the things they threw at us, we had a few moments ourselves in the game as well. I think it was almost cagey, two good teams cancelling each other out in the first game, which is understandable, and we take the point and move on."
Chelsea's defensive resilience may have come at a cost in terms of their attacking play, with the Blues managing just one attempt on target during the first half.
Their attack did improve after the break, with Chelsea ultimately mustering six attempts in total, with four of those hitting the target.
