Chile had their best-ever coach, their best footballing generation and also home advantage in Copa América this year. Everything conspired in their favor for the title -- their first in 99 years of competition, even before facing the historically bad penalty takers in Argentina (Brazil seems to want to hold this title as well), and managed to grab the so-deserved trophy.
But a problem arose from Chile making such a deep run. Alexis Sanchez, arguably Arsenal's most important player last season, has played in all six matches for Chile, including the 120-minute long final. And according to the Telegraph, Sanchez will be given 3 weeks off after not having a single week to rest, as he joined the Chilean national team as soon as the season ended for his club in England.
Another problem for Arsenal is the Community Shield. The Gunners, FA Cup winners, will be playing against Chelsea, Premier League winners, in a friendly on August 2nd. Sanchez will be joining Arsenal's training camp on July 27th -- less than a week before the match. He'll probably arrive at the club unfit for the match, and therefore he's set to miss it. He might be on the bench as an option for Wenger, but it is highly unlikely that the French manager will risk starting an unfit Sanchez -- even in a match against Chelsea.
The Community Shield is certainly not as valuable as a League Cup or a FA Cup title, but to me, any silverware counts. Getting a new trophy in the cabinet isn't a bad way to start the season.
