France's performance in the first half of the 2022 World Cup was not at all satisfactory but when France picked up several players from the starting XI, France bounced back against Argentina.
When Ousmane Dembélé, Giroud Griezmann were taken off the field in the second half, France played brilliantly and Mbappe was unstoppable. If Karim Benzema had been present in the final match, France would have gone a step closer to winning the World Cup. Only one save at the very end of the game denied France the World Cup and their penalty shootout was not at all satisfactory which saw them lose the final match. France can do quite well with the team they currently have.
The biggest problem if you ask me was the defense. They were too far up the pitch in both goals and took time to get back. Look at the first goal, it was a penalty and a fault of the defense, you do not do that on the world cup finals, it wasn't like a tackle or anything neither, it was just pure mistake. Look at the second goal, defense was nowhere to be found when Argentina started their counter attack, you see them get the ball, start hitting back already, stop with the offisde trick.
All in all I believe that we are going to probably see them have better defensive understanding, they need to be planted better and they need to do better. Offense was great all game long and I do not see any issues with that at all.
