Liverpool's hold of the top position looks shaky at the moment and the reason is the injuries you mentioned. They have less tournaments to compete so I guess that helps them too. I still think City has a better squad depth than LFC but we'll see how this goes. Maybe we'll see the gap to widen in the next ten games.
Seeing a team that has difficulty maintaining its position so that it remains in first place at the top of the standings is very difficult to do; therefore, there are many teams that cannot control their emotions on the field and do not compete calmly, so it will be difficult to win and maintain their position at the top. of the standings. However, Luton Town's match hasn't started yet, so you have the opportunity to set up a good strategy to win this match because Luton Town shouldn't be a tough opponent and it will be easy for Liverpool to win.
When a team is competing in the strongest league in the world, I think it is pretty normal to feel the mental stress and sometimes it gets to them. As a team whenever they lead the standings, they also know that everyone behind them is most likely going win their games and then it raises the pressure additionally. That's why I think the Premier League title is probably to be considered on one level with the Champions League or maybe almost as difficult. There is Manchester City, Liverpool, Arsenal, Tottenham, Chelsea and some others that are not so bad. I know that Chelsea is out of shape, but when most of these teams are about to peak, it's so hard to win the Premier League title and you can almost be sure that at least two teams are at their peak while almost none of the games are easy anyway.
