Unai Emery does not want to cash in on Matteo Guendouzi.
Paris Saint-Germain are said to be monitoring the midfielder and have been linked with a £60 million move.
But Emery said: “His development is like we want. He has a big ambition, big quality. Sometimes we need more quality with him and for him to be more stronger in midfield.
“But his development with us is very important and he’s playing with big consistency. His quality is very impressive.
“I am surprised (with the link). I don’t want this.”
