Wales coach Chris Coleman says he won't rush to cap Liverpool whizkid Ben Woodburn.
With England interested the move also protected the teenager's future.
But Wilson has not featured since and in regards to Woodburn, Liverpool's youngest ever scorer, Coleman said: "We will be careful. Harry came in when the squad was decimated to give him a taste of things. To be honest, I think he struggled a bit afterwards but it's good to see he's now back on track.
"You have to balance between protecting them and pushing them on, but we're delighted with the progress Ben is making."
