As Everton reflected on their 4-0 dismantling of Manchester City, one wonders what the club's head of performance analysis Laurence Stewart made of it.
Stewart used to work in a similar role at City before Pep Guardiola took over but departed for a promotion at Everton fearing, rightly or wrongly, that he would be marginalised.
Stewart is relevant to the story of City under Guardiola because he is part, albeit a very small one, of the bigger picture of what has happened at the club since the former Barcelona and Bayern Munich coach took over in the summer.
