Manchester City are really in top form at the moment, so I think it will be very difficult to contain Manchester City. Leicester didn't have a good chance to try to stop Manchester City today, even Leicester had been 3-0 down since the first half. Because of that, it looked very easy for Pep Guardiola to rotate some players in the second half as Haaland and John Stones have been replaced by Alvarez and Manuel Akanji.
Manchester City will likely play it safe in the second half because there are still important matches waiting for them in the Champions League. So I think Pep Guardiola is getting excited to look forward to the second leg of the Champions League against Bayern Munich because Leicester are looking easy to beat.
Leicester doesn't have the strong defence so it was likely they are gonna concede in the first half. With such an easy scoreline they can switch players and can save their energy for their CL matchup with Bayern but then again they are having a good lead there as well. City are performing dominantly and right now everyone seems like an easy opponent before them. I just hope that somehow Arsenal keeps up their gap till the end in the PL.
