Büttner made only his seventh start this season for United in victory at West Ham United on Saturday.
He told manutd.com: "I don't know if people saw this, but before the game at West Ham, Patrice spoke with me for about five minutes on the pitch. He helped me a lot.
"It's not like he was hoping I wouldn't do well. He helps me every day and I appreciate that. He's been in football for many years and I've only been here for two years. In England the football is difficult and Patrice has helped me a lot."
