Newcastle are already said to have had a bid of around £10m for Murphy rejected.
And now Norwich manager Daniel Farke has gone on to state that he expects the 22-year-old to stay put at Carrow Road beyond the end of the current transfer window.
Farke told the Evening Chronicle: "I don't take part in the speculation or rumours. Jacob returned on Saturday and did some tests. I'm looking forward to working with him."
