LONDON : Ange Postecoglou will bring up a half century of Premier League games in charge of Tottenham Hotspur on Saturday with the jury still very much out on the Australian's impact at the club. His side are in 10th place in the table ahead of their trip to champions Manchester City and defeat would provoke further debate about Postecoglou's progress. The 59-year-old led Tottenham to fifth place in his first season at the helm - a solid improvement on their eighth-placed finish the season
