Many teams are equal in strength, this makes bets on the outcome poorly predictable (but undoubtedly interesting will be the games themselves). However, if you dig deeper, then in the line you can find good options.
I doub't that any of these 18 european teams takes this preseason friendly tournament too seriously.
I guess that this tournament games are only intresting(to the spectators) if the matches will have goals in it ...
It's cool to see the big players and the big clubs playing in the US, but they aren't all trying extremely hard. Many of them had busy summers the are just prioritizing returning to full fitness in these few weeks before the league and UEFA competitions begin in Europe.
interesting for the teams, namely with good teams, preparation goes - well, you see more - well its shortcomings. And for fans is good to watch these matches, especially now after the World Cup when there are no matches for watching!
