That's the thing with international football, the way UEFA/FIFA advertise them leads people to think it will be a super massive clash of titans, while really only a few games will match the quality of ties between the top-5 teams in every major European League.
Still awesome don't get me wrong, but I think the players should take it more easy, I mean unless you're playing Spain or Germany, the average team, especially in the group stages is in the international equivalent of West Brom, perhaps only slightly better.
Carroll and Walcott both looked class last night, we all know their true quality and how (in)effective they are against Prem-defenses.
Same thing at the last World Cup, both Suarez and Forlan looked world-class as they were scoring and creating chances like crazy, teams were fooled by their international performances and put them in their team on fat wages. Forlan and Suarez have not scored more than 20 goals between the two of them this season.
I think the domestic leagues tell a lot more about a player than tournaments, any player can lift his game for one match and shine, the true value is consistency, being able to repeat the same level of performance regularly and against top opposition.
Then obviously sometimes the opposite happens and you have players who shine for their clubs completely choking internationally.
