Milan's performance has been poor since the start of the Champions League. They have won just one match. However, their performance in Serie A is very good. Their main goal is the Serie A title. So in the Champions League matches, they did not form a team with any different strategy. They didn't think the Champions League matches were important. Seeing their performance, it seems so.
I think so too, but Champions League is not that easy if comparing it to countries club leagues, UEFA Champions League is tougher and players put more energy. If home league is what they want to focus on, they have the time now. But all other clubs in their group stage are also good, like their giant Liverpool, Atletico Madrid is not in good performance but not that poor.
Atletico is crazy. Start the last game bottom, finish the group second.
When all other clubs were playing rubbish. Liverpool had 18 points which means it won all its group stage matches while other clubs had low points, Atletico Madrid had just 7 points and was the second on the table, it was not still encouraging at all.
