When it comes to scoring goals Lewandowski has always been good, he has always known to be a goal scoring machine. Lewandowski is a great player and it is possible that before the season end he will increase the amount of his goals. Lewandowski is one of the reasons of Barcelona victories in their games.
With Injuries ruining the season of Pedri and Dembele we can clearly see that Lewandoski is struggling a bit when it comes to scoring goals. Pedri and Dembele are Barcelonas most creative players, they create a lot of chances for Lewandoski. So its totally possible for Benzema to catch up and even overtake him. Benzema is also a good goal scorer and it seems he begining to get back last season form.
Its going to be fierce battle between Lewandoski and Benzema for the pichichi award this season. If both Pedri and Dembele gets fits and starts playing soon then the chances of Benzeman winning the pichichi reduces even further than it already is now.
Pedri and Dembele are one of the best players in the Barcelona team. These two players are able to play an incredibly good role in the attack. Barcelona have made a huge profit by adding Lewandowski. Ever since he joined the team, he has been superb scoring more or less in every match.
