Players who propels the managers tactics is key and the same goes with manager being flexible with his tactics to accommodate the available players in the squad. Well, Osasuna defence was something else and that penalty awarded to Kylian Mbappe shouldn't have been a foul or penalty. He was seen stepping on the defender. If this is how they intend playing, Barcelona or Atletico Madrid will win the league by January. 
Departures and retirement of Cristiano Ronaldo, Benzema, Bale, Casemiro, Kroos and Modric are like parts of an official ending announcement of Real Madrid's golden era in modern time. Several seasons later, they still managed to win Champions League and La Liga with Rodrygo, Vinicius, Valverde and still had Kroos in their club but the last season shown many problems in their squad.They failed to replace Toni Kroos, Modric could not contribute too much, while the super star player Mbappe only performed well individually but at a team level, his appearance in the club actually created many issues. It seems Xabi Alonso could not resolve those headache problems during the summer and in the first match of season. Mbappe and Vinicius will continue to be main causes of Real Madrid problems in balance between attacking and defense in this season.
