Plea to Blackburn

I used to like Ronaldinho a lot. He was good at what he did. He had a nice line of shoes with Nike.
But Ronaldinho is 30 now. He's not as good as he used to be. He's been at AC Milan for a couple years now and hasn't made much of an impact there in my opinion. Pictures a few years ago of him doing some training showed a bit more of a belly than most footballers should have.
Now Blackburn Rovers is reportedly making a 6.2 million bid for Ronaldinho. I don't think its a smart idea for a club like Blackburn who wants to win. Dinho is 30. He's basically past his prime playing years. If he contributes anything of worth to the club then great, but I don't think he will.
If Blackburn just want a big name player on the bench to bring recognition to the club then he's a good deal, but I don't see Blackburn spending money in that way.
Blackburn, if you want to rise in the Premier League rankings from the #12 spot you are now then invest in some unknown players who can become famous and lead you to the top of the table instead of a past his prime big name.
