It's an important match but not that important, not even as prestigious as the Coppa final. It isn't at a great time of year, and is even worse during a tournament summer. We're talking about how we are struggling for great form and fitness, and our Confederations Cup players came back even later than the others, so they won't be near top form until probably several games into the season.
We can put in very capable players to replace our 'starters', that's why we went out to buy good depth. Players aren't robots that you can just turn on and off, lack of games or tiredness seriously affects performance. Considering the concentration levels needed to play in this team it makes sense to field those in the best condition.
It's a really bad time of year to judge players, we'll see who is doing the business a month or so into the season. You see it with teams and many players, the season can start off very deceivingly.
