I know Luka Modric is still energetic enough to continue playing professional football at top level but do you actually think he took a good decision to play another season with Real Madrid? I'm a Real Madrid fan and is a big admirer of Modric's style of football but to I was expecting him to leave the club after winning the UEFA Champions League and the Spanish La Liga title last season with Real Madrid bht just like you, I was surprised that he decided to stay back for one more season. I think the Croatian doesn't want to play club football for any other club again before his retirement and maybe wants to retire from football next summer which is why he decided to extend his contract with the club for one season so he retires from football as a Real Madrid player.
I am happy to see today news because Luka Modrid has been given one more chance to stay with Real Madrid this season. Of course, after Toni Kross announced his retirement, of course Real Madrid lost one of their best players, but with Luka Modric surviving on a contract for the next 1 season, of course the fans weren't too disappointed because they could still see a player who was full of experience in the Real Madrid team this season. .
If you look at Luka Modrid's age, of course he is very old and the next season will be his last season with Real Madrid. As you said of course he will announce his retirement at the end of this season. We only see him for one more season and for Real Madrid's young players they still have seniors who can give them a lot of experience for the next season.
