"It surprises me that Jamie is not a regular in the England team," said the Liverpool boss.
"It was an outstanding performance from Jamie. When defenders like Jamie have to play against world-class players like Ronaldinho, it is important that they do not make mistakes - and he didn't.
"He is such a good defender against the very best players and, yes, it is a surprise that such a really good defender does not play every game for his country."
