The Yorkshire giants went into the game having registered four wins in a row in all competitions, but Bielsa witnessed his team twice go behind at the Liberty Stadium.
However, while admitting that improvements need to be made, Bielsa has suggested that he had been left impressed with his players as they salvaged a point in South Wales.
The Argentine is quoted by BBC Sport as saying: "We didn't defend very well and this did not allow us to dominate the game with regularity. In the first half Swansea dominated the game.
"It took us almost 25 minutes to get into the game. After their second goal we had greater stability. After we scored again at 2-2 we dominated the game. We have won this game and we have lost it too. It was a nice game to watch. There are some important aspects we have to correct."
Leeds sit at the top of the second-tier standings ahead of six fixtures which will take place on Wednesday.
