You can't read too much into preseason matches or indeed the Charity Shield - a match that is neither a friendly nor major silverware (unlese you're Jose Mourinho) but has a high profile due to the usual opponents. Having said that I'm sure that beating strong Man City lineup is good for team morale going into the season, even if this team are experienced enough not to let it go to their heads.
Liverpool have now refreshed their front line, a necessary but always risky and expensive process. There is truly no replacement for the Salah, Firmino, Mané trio at their historical best. But that doesn't mean the current group can't be just as good in their own way, and of course Salah may have several years left at his peak. Bobby Firmino is clearly past his best but is still an excellent squad player who is universally liked and offers something unique. And of course we now have to see how things play out between Jota, Díaz, Nuñez, and Carvalho (the latter probably a bit part player but one for the future, as they say). The raw materials for a fearsome attacking unit are all there.
On paper I expect another year of Man City winning the title. Why would anyone assume otherwise? But Liverpool have done well in the transfer market and retain the core of a world-class, experienced squad, so I expect to see them finishing second after pushing Man City hard again, coupled with a good European campaign. And of course if Man City stumble Liverpool will hopefully be right there.
More interesting perhaps will be to see how the rest of the top six shake out. To me all of Spurs, Arsenal, Man Utd, and Chelsea are wildcards. All of them have made some major signings and of course Man Utd now have a permanent manager in the hot seat. But only two of them are likely to qualify for the Champions League.
I am looking forward to starting the season with a very sour-looking CR7 on the pitch for Man Utd, wishing he were somewhere else. Mind you, he'll still probably be scoring goals, but even so I bet ten Hag also wishes Ronaldo were somewhere else.
