Bielsa caused controversy when Phillips was taken off at half-time against Brighton last weekend.
The England midfielder played 90 minutes against Crystal Palace on Tuesday, with Leeds stealing a late 1-0 win.
Speaking after the game, Phillips said: "Massive relief, I think we deserved the win, created some good chances in the first half. We got a little bit lucky in the final minutes with the handball. Very happy.
"There is always concern when you are creating chances and not scoring. We started struggling this season so we are happy to get the three points.
"Rafa is a very good players and oozes with class, so I didn't expect anything else.
"It is a massive win for us, we are very happy and have to try and go on a run of games now - we have a tough run of games before Christmas.
"I will play any position the manager asks me - if he wants me to play centre back I will play centre back, if he wants me to play goalkeeper I'll play goalkeeper. I respect him so much I will never fall out with him.
"I saw a lot of things on social media and TV that me and the manger had fallen out, it's never been the case and I wanted to put that to bed."
