Newcastle sports chief Dan Ashworth cannot rule out taking legal action against Sandro Tonali's former club AC Milan.

The Toon are exploring whether Milan sold them Tonali knowing about his betting investigation.

Ashworth said: "It's really difficult for me to get into what other clubs do or don't know. All we can do is look at our own internal investigation and internal process.

"It's a really difficult question for me to answer, I just don't know."

In reaction, Milan declared in a statement: “We first learnt about Tonali's addiction through media reports and what we know is only what we read. We don't know anything else."
