Why Man City must ditch Ronaldinho plan

Manchester City's pursuit of Ronaldinho has been an interesting sideshow to the summer of speculation - and for their sake let's hope it becomes nothing more than that.
The latest development, coming from a source that has proved almost 100% reliable on all matters Manchester City in recent weeks, is that an e-mail containing an offer for £22m has been sent to Barcelona, and no doubt very gratefully received.
Barcelona would presumably wrap Ronaldinho in cotton wool and supervise his safe arrival to the gates of Eastlands for that sort of cash.
Ronaldinho's arrival at Manchester City would undoubtedly cause a frenzy of interest, but what happens when the novelty wears off?
I, and many others, fall into the "believe it when I see it" category when it comes to the idea of Ronaldinho playing for Manchester City.
And while the notion of Ronaldinho plying his trade in the Premier League would have been a truly fanastic prospect two or three seasons ago, I genuinely believe AC Milan would be doing City a huge favour if they outflanked them on this deal.
What would City be getting for their vast transfer outlay and a wage packet that has been speculated upon as being around £200,000-a-week?
They would get someone who was once the world's greatest talent, but is now 28 and has to answer huge questions about his form, fitness and attitude.
