That £7m release clause has been in his contract for the past 2 transfer Windows, I remember Harry was the first to let that one out of the bag last January. After he went public with that I was pretty surprised that we never went in for him then to be honest, especially as he was in such hot form then.
Newcastle did sign him on a free transfer, so have made a tidy profit. But yeah , it is strange that the clause was in there in first place as it seems very few players in the EPL seem to have release clauses.
