The fifth round of games in Premier League is over, and it served some unexpected twists and turns to the fans of the league.

In fact, this game-week could have a long and lasting impact on how the Premier League pans out in 2019-20. Here are our five key observations from this week’s action.

Manchester City are in trouble

No one saw it coming. Many had feared for Norwich City, but the Canaries produced arguably the biggest upset of the season. Norwich’s win over the champions could have far-reaching consequences for the title race and the relegation battle. The result has not only breathed life into Norwich’s campaign, but it has also raised doubts about City’s title credentials. The champions looked hapless with Aymeric Laporte in their defence and if Pep Guardiola doesn’t find an internal solution soon, Liverpool might run away with the title.

Tottenham are back, surely

Tottenham made an underwhelming start to the season, and many were quick to point it out. However, manager Mauricio Pochettino had always maintained that his team was destabilized due to the transfer window. It appears that Spurs have finally found their rhythm after the closure of the transfer window. Their home game against Palace was supposed to be a tricky one, but they made a mockery of the competition with an easy 4-0 win.

Youngsters are firing for Chelsea

Chelsea look very shaky at the back, but there is no doubt that boss Frank Lampard has the youngsters firing on all cylinders. Tammy Abraham and Mason Mount have been the pick of the lost, and they justified Lampard’s faith in the 5-2 thumping of Wolves. Abraham scored the first Premier League hat-trick of his career and Mount also added one to his tally. It’s still early stages in the season, but Chelsea youngsters promise a bright future for the club.

Lack of squad depth very apparent at Man Utd   

An injury-plagued United side did well to register a 1-0 home win over Leicester City. Following the recent disappointments, it was a huge result for Ole Gunnar Solsjkaer, but it also laid bare the lack of depth in United’s squad. During the game, the Norwegian had only one senior member on the bench to call upon in Fred. The situation could get worse once the Europa League starts this week.

Unai Emery’s time is up at Arsenal? 

Unai Emery endured arguably the most difficult 45 minutes of his time at Arsenal during the 2-2 draw at Watford. At one point in the game, the Gunners looked set for three comfortable points with a two-goal lead. However, the game turned on its head during the second half. Individual errors combined with inexplicable substitutes from Emery meant that the visitors were lucky to get away with a point in the end. Arsenal players looked like headless chickens during the second half as they endured waves of Watford’s attacks. The result caused a bit of an uproar among the fanbase, and the majority of the criticism was aimed at the manager.
