MANCHESTER, England (AP) — After two games of the season Manchester United sat at the foot of the Premier League with no points and a goal difference of -5. Roll the clock forward five months and manager Erik ten Hag has turned the club’s fortunes around to the point that a win against Arsenal at Emirates Stadium on Sunday will spark genuine belief that an unlikely title challenge is on. It has not been an overnight success for United’s Dutch manager, who had to contend with an unsettled Cristiano Ronaldo while also trying to knit together a much-changed squad after taking over a team that finished sixth last season and 35 points off champions Manchester City.
