Pardew believes Ashton can play in the same role as Wayne Rooney just behind two strikers.
Pards told Sky Sports, “I think we have two players here with a very genuine chance (of making the England squad), perhaps more than that.
“Ashton was top drawer on Saturday. David Moyes would say that as well because he gave them all sorts of problems.
“He took a knock that slowed him down in the second half.
“The advantage he has got on other strikers is he can play in a deep role and link things in.
“Look outside of Wayne Rooney, if he got injured, who would do that role?
“Dean could do it well. He's only just doing that role here but he's been terrific.”
