#3. Renato Sanches
Another player who could potentially become one of the most expensive signings of all time is Renato Sanches. Sanches made the big money move to Bayern Munich several weeks ago after publically turning down the chance to join Martial at Manchester United. Sanches was a surprise inclusion into the Portuguese squad but injects some much needed youth into an aging team. Sanches is one of a number of exciting young Portuguese midfielders which the country needs to build their team around in the coming years.
