No idea how well he's playing for Milan as I have seen very little of them this season, but I sure do not put as much weight as some do on national call ups. Unless the player is a regular player for his nation, then an occasional call up really doesn't mean as much as newspapers try to make it sound - calling an once capped crap player a "Brazilian international" seems to be one of their favourite tactics to spice up some rumours. Lots of terribly average players have been called up and played a few times even for the best national teams such as Brazil, Spain, Germany, Italy and so on.
All I really have to do is look back at some of the England teams over the years.
That said, I think it's reasonable if a players having a good season, to give him a shot and see how he does.
On the other hand, Carlton Palmer won caps
Still can't believe that one
As for Suso, he's a gifted footballer.
It's just a pity he's not as good as he thinks he is.
Matches are won and lost on the training pitch, and in the players heads.
By all accounts, Suso thought that was beneath him.
Good luck to the lad, but he could have been so much more right now, if only he didn't let his ego get in the way.
