Think it's a bit unrealistic to think that hg is not part of the attraction.
Pep clearly wants a full squad next season so we have to have four hg players.
Whereas we don't need them in any specific position it looks like Walker may well be the best player available.
The only players who have looked better to me recently in an England shirt either belong to us or are called Alli or Kane.
This is not to say Pep doesn't rate him, just that I suspect hg is part of the attraction and probably a reason why we will pay a premium price.
