If regeneration is used, will it meet expectations? What is feared is that it will disrupt the current standings, because it will have an impact on AC Milan's position at the top of the standings temporarily, and will certainly take quite a long time to form a new regeneration, although Giroud is still in good form at AC Milan, which doesn't mean that AC Milan will sell him and in my opinion that is impossible for Milan to do at this time, what Milan needs now is to improve their Champions League and Serie A standings to maintain their current standings..
Olivier Giroud is 37 years old at the moment. He has got very old but thanks to his being a quality striker he still makes a big contribution to Milan - 4 goals, 3 assists in 8 matches in total. But after completing this season I expect Milan to part their ways with him finally. Or they can at least give more chances to some other strikers in the starting eleven.
Milan have only a few 30+ year-old players who are playing actively now. They are actually a quite young team now but I really like their performance so far. This doesn't cause them any problem.
Of course they still couldn't get a win in the Champions League but they will start to win there sooner or later. They should be able to be competitive for the Serie A title on one hand.
