Frings is not your traditional holding midfielder, and thats a position that he played in during his time at Bayern. He wasn't also settled that much at Bayern so he couldn't produce his best game.
With Bremen you could see that hes being played in a diamond shape or part of a 3 man midfield.Where he doesnt need to distribute the ball to the midfield.
Hes a hardworking midfielder who has a great shot and could even provide you with the occasional assist here n there.
His qualities were shown during the WC as a world class midfielder, with a big effect as the game he didnt play in(against Italy) the German midfield was unbalanced

That's absolutely true. He's not the player some think he is. After Micoud's departure he's taken most of his roles, too. He works well in both defense and offense. He's been good in every game for Werder this season other than Diego, who still needs to improve, remember he is still very young.
But Frings won't leave anyway, you can be pretty sure about that. He has made his experiment already in Dortmund and Bayern.
Yes he is, for all those who are thinkin about Quaresma or Ribery, I'd really suggest they watch Bremen games this season. Whether they win or lose, Diego is always playing very well.
I'd consider Ribery for winger with his pace and all, but without a doubt Diego would play a much bigger impact on the team. I think above all of his abilities he's an intellegent player, you wont see him dribbling around a player twice!
Diego's performances are not that consistent. After the great euphory in autumn we can now see a different side of his play which was easy to ignore when everything else was working well. But since the winter break, Diego is not playing better than the others in Werder. He's keeping the ball too long, tries too much on his own. At the moment it would be better for Werder to still have Micoud, who is a real playmaker rather Diego, who is a dribbler and does not take the lead
yet. Often he leaves it up to Frings.
But he's young and will improve.
