In the beginning, Real Madrid was not very productive in scoring goals, we know before the UEFA International break Madrid was not good but after that they were great and rose slowly, Lewandowski is indeed the top goal scorer for the time being, But I'm pretty sure that Mbappe and Real Madrid are now getting more solid in their matches, I'm pretty sure they will get more goals, this will indeed be a very interesting competition in the race for goal scorer in La Liga, Mbappe's absence for a few days is indeed an opportunity to catch up, but I'm pretty sure Mbappe will stand at the top at the end of the league as the top goal scorer.
It is unfortunate that Mbappe suddenly got injured when his performance was good with the Madrid team. 5 goals in 7 matches, if he was not injured it would have been very possible to catch up with Lewandowski's goal tally.
Reportedly he must be absent for 3 weeks. it could be a faster recovery, but it could also be longer. hopefully, Mbappe will do his best in the recovery process. The sooner the better, because Madrid will need him in several important matches. not to mention Madrid's tight match schedule which of course could affect the fitness of other players.
