Jhon Duran has become one of the Premier League's most dangerous weapons off the bench. The Colombian's numbers as a substitute are extraordinary — goals per minute, impact on games, physicality when fresh legs are needed most. But there is a growing debate at Villa Park: should Emery start him in the Europa League quarter-final against Bologna? 🦁 Arguments for starting: Bologna's physical defence vs Duran's strength is a real match-up 🦁 Arguments against: His impact element disappears if teams can prep for him from minute one Emery knows this better than anyone. He has used impact substitutes brilliantly throughout his career. The bet is Duran starts on the bench — and changes the game in the 60th minute. Either way, Bologna will need a plan for him. That's a problem for the Italian side.
