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.

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.
Talking about assists, no player comes close to Lewandoski when it comes to assists, he has assisted more players this season than any other player could, and as the number 1 striker forward for the team, its the responsibility of other players to provide assist for him when there is need to score a goal. Though Dembele is a good winger and is the only player that comes second with good assists for Barcelona, not sure of Pedri, even Balde has more assists than Pedri this season because he has zero assists this season.
Real Madrid has rained a spree of goals against Valladolid, this ought to be what they were supposed to do in the middle of the season to overcome Barcelona in the standing and they are only doing that now, maybe they will end up with a golden booth if Benzema multiplies his effort but they are far from lifting that trophy.
