From starts, he's played in games they've won when coming on. There's a good argument in that tweet about it
Seeing as he won't have started many games for City, when was the last time he won when starting? Could be absolutely ages ago
Must be league only, he started in the cup for Sunderland in 2015 and they won 6-3 http://nr.soccerway.com/matches/2015/08/25/england/league-cup/sunderland-association-football-club/exeter-city-fc/2139145/
In the league, his last win from starting seems to be 7th May 2013, Man City 1-0 West Brom http://nr.soccerway.com/matches/2013/05/07/england/premier-league/manchester-city-football-club/west-bromwich-albion-football-club/1294005/
