To illustrate the point further, there are 71 players who created more open-play chances than Sigurdsson in the Premier League last season. That included Kevin Mirallas and three other Everton players. Ross Barkley created 54 such chances. Sigurdsson managed only 25 - the same number that Gareth Barry and Idrissa Gueye produced in fewer games.
Even from set plays, it is uncertain how much of an impact that Sigurdsson might have at Everton given that Barkley, Mirallas and Baines shared the team's set-piece duties last term, creating 51 opportunities in the process - only one fewer than Sigurdsson.
