Real Madrid score goals but we can't say that they don't need Mbappe just because they can. After all, no one can say no to Mbappe, one of the best players in the world. More difficult fixtures will come for Real Madrid, then they will give the real test. Champions League game is one of them. Benzema is on top of his form, if he got injured or something happened to him there is no replacement at same level.
Speaking of injuries, Braithwaite will going under surgery for his left knee. He will be out for at least 3-4 months, that's a big blow for Barcelona. Now all pressure is over Memphis. Fati, Agüero and Dembele faced similar things, Barcelona can't play injury-free players, we couldn't see an ideal eleven without any injuries yet.
I think Real Madrid don't really need Mbape again,they were scared from the begining thinking they won't be able to meet up the challenge for European trophy that was why they wanted Mbape by all means,,but it seems that fear is out now.If you look at their playing pattern,you see that they are a very strong team,and don't need any further more addition to make them strong.And I am very optimistic about their performance in the champions league this season,that they will surprise people.
In 4 matches Real Madrid was unbeaten and managed to score 13 goals, this means that Real Madrid's performance is very good and also
very productive. Looking at the data, Real Madrid should not need Mbappe anymore, but until now Mbappe has not extended his contract with PSG.
This means that next year Mbappe can be obtained for free, so if Real Madrid want to get Mbappe there is no need to spend money to buy it.
Because with Real Madrid's already good performance, the need to bring in Mbappe is no longer urgent.
