The 0-3 victory over Leipzig is a good advantage. Xabi has made this change look apparent in their 3rd match, they played more organized. It seems Xabi wants to set a record and prove himself to win the first trophy. One of the proofs is Modric, who has agreed with Milan to still be brought to the Club World Cup. Xabi seems to be maximizing all the available players.
I think you meant FC Salzburg because Leipzig has not played any match with Real Madrid on this tournament and they're not even on this competition. So actually Xabi Alonso did what he was brought to do, the club that wanted him to look bad on his strategy was AI Hilal because they were exploring what he assigned real Madrid to do and unfortunately for Real Madrid they had just started with Xabi Alonso so it had to be draw but after then non could challenge real Madrid again and it also increase there chances of more goals, there second and last goal was never beyond or below three goals.
