Actually, I think Liverpool are the only team in the Premier League that is capable of challenging Manchester City this season, and, having won the Champion's League - the one trophy Pep would kill for - can only enhance their confidence.With the summer saturated with fake tournaments, it's hard to gin up any enthusiasm for the Community Shield. Liverpool's front line are short on rest, and while the squad is mostly intact it seems mad to throw them into a high-profile but competitively meaningless match right at the start of what will hopefully be a very competitive season. I've always found the Community Shield to be a fun "curtain-raiser" (to use a phrase Klopp recently encountered)...when my team isn't involved.
I know it sounds like getting the excuses in early, but I'd rather see Klopp rest players here. He'll get a ton of bad press for it, and Liverpool will likely lose (Man City will always have a deeper squad). But they'll likely lose anyway. On the other hand, if, say, Virgil or Firmino or Salah picked up a long-term injury in this match...I don't even want to think about it.
A lot of pundits are opining that Liverpool will not be able to push City as close in the league this time around. I think the odds are perhaps in favor of that outcome, though I am hopeful Klopp can helm another successful Champions League campaign and keep the club in the top two in the league. He's never had much interest in the cups, so I expect to get knocked out of those relatively early again...unless some of the young players / squad players like Brewster step up and make things happen.
However, I agree with you completely re the Community Shield (in my mind, I still think of it as the Charity Shield); it would be silly not to rest players - especially those who have had a long season, and perfectly ridiculous if one of those players picked up a serious injury in what is, after all, while a curtain raiser, still a meaningless match.
