No point in discussing the fraudulent ass tackler - he is here to stay, unfortunately. Just like the frozen kebab, he will leave when he decides to, or when his contract finally runs out (unless he's given another extension).
Now, is he a good defender? The word good is subjective, and by modern standards, he's decent. However, had the traitorous ass tackler been playing in the era of greats like Scirea, Baresi, Bergomi, Maldini, and later Nesta and Cannavaro, he wouldn't have seen the likes of a football pitch, least of all for a team like ours.
