In his latest Sky Sports column, Paul Merson argues that Tottenham, Manchester City, and Manchester United all have defining matches this weekend, despite it being early in the season. Tottenham are still without a win or a goal in the Premier League after three games and will play against an unbeaten Everton team on Saturday Night Football. If Spurs lose, Merson warns fans should start worrying about another difficult season, but a win would put them on four points and build momentum. Meanwhile, the Manchester derby on Sunday sees Michael Carrick's inconsistent United side take on a City team facing their first big test in the post-Pep Guardiola era. Merson states he still does not see Manchester United in his top five, criticizing the squad as not big enough and defensively nowhere near good enough. He adds that if United beat City, they are flying, but if they get beaten, the season is once again in the balance. He notes that other teams are winning around them, making the result crucial for United's confidence and league position.
