I disagree with your statement. Maldini's end was respectful. His only problem is that he played for Milan. There is nothing wrong with a player to continue his passion of football even if not contributing a 90 min game. If matters gets to it and del piero is used as a sub (like Giggs for an example) then so be it. But we are talking about a player who is being used in the starting 11. Juventus would be in complete insanity not to renew his contract.
Dear,in Maldini's final match in San Siro against Roma,fans was chanting against him,go n ask any milanese if they wanted Maldini to retire since 2006 or not?
It doesn't mean that Alex is a starter so he is the same Alex as before,we all now that Alex is starting cos he is better than all the others in the attack despite he is 36,and if Juve had a WC SS then Alex would have become like Giggs as u mentioned,only used as sub.De Ceglie and Grygera are also starting,does it mean they are good?
We all enjoy to see Alex playing,but he should choose the perfect time.Remember Platini,he retired at the age of just 32,he could continue for sure,but he had choosen to end his career when he was still shining.
