Leeds United boss Marcelo Bielsa was delighted with the efforts of his players for their 0-0 draw with Chelsea.
Bielsa felt they became stronger as a the game went on.
He said, "Evidently, we played against a team that is superior to ours. But in the second half especially, in the first half less, we did what was necessary to play a balanced game.
"And at the end of the game, the chances that both teams had were similar. It's true the superiority that they showed in the first half was superior to that what we showed in the second half. To be able to play a game like we did today, we had to make an enormous effort."
On his much-changed back four, Bielsa also said: "Sincerely, it's not difficult. The defensive line, in particular the centre of it, those players have been the ones playing at the highest level for us up until now in this season.
"But strangely enough, we are one of the teams who concede the most goals. Which puts into manifest that they've done some things with the organisation that I have yet to resolve. Today, for example, Pascal, Ayling, Llorente and Phillips played a very correct game."
