Goalkeeper coach Tony Roberts has left Wolves.
Roberts is expected to join the coaching staff at AC Milan.
Wolves chief Matt Hobbs said: “Tony will certainly be missed, but it's an unbelievable opportunity that he has received so we'd never stand in his way. He's been up front and honest about the contact has had, and it's a great chance for him and he goes with our full support.
“Tony's built the best goalkeeping department we've ever had at the club, in terms of the coaching available to the boys. We've done a lot of recruitment in the academy through Harry [Hooman] and his team.
"The best thing I can say about Tony is what he's leaving behind and the work he's put in should make this change relatively seamless. Of course, Julen [Lopetegui] is disappointed, but understands why Tony wants to take the opportunity."
