Unai Emery has transformed Aston Villa once. Emery has got Villa to overperform for most of his three-and-a-half years in charge but has to cope with a summer of change at Villa Park. Villa have sold Morgan Rogers to Chelsea for £117m - a record move for an English player - a week after Youri Tielemans joined Manchester United. Lucas Digne is expected to join Paris St-Germain and Villa could still have their resolve tested by Arsenal for Ezri Konsa. So after ending their 30-year wait for a trophy with May's Europa League win, can Emery continue to produce his magic?
