We saw Liverpool's dominance in the Premier League last season. At the end of the season, Liverpool was 10 points ahead of Arsenal. This gap would have increased even more if Liverpool had given their full effort to win the last 4 matches. After securing the Premier League title, Liverpool gave their full effort to win the following matches. Liverpool secured the title long before the end of the season.
However, we will not see such a scenario next season. City is trying to increase their strength. Guardiola will make every effort to regain the top spot of the table. Liverpool will definitely try to dominate the Premier League again. On the other hand, Arsenal has occupied the second place in the table for the past few seasons, unable to win the title. This team will try to win the title again. The fight between Liverpool, City and Arsenal will be more intense next season.
Since they already won the league long ago before the final match day, personally, I see no reason why need to risk themselves to injury since they've already won it. Had it been they were gunning for a record breaking point of 101 points then they would have gone for it. Talking about Pep, I think his already made four signings already in this transfer window. I think his coming to compete for the trophy with Liverpool this time around since he missed out last season.
