#1 Karim Benzema
The critics were harsh toward the French striker at the beginning of the season due to his poor 2017/18 campaign. It was expected that Bale would take the goalscoring load after the departure of Ronaldo but Benzema was truly the standout player in the current campaign.
With a string of powerful displays, Benzema has been one of the most decisive players in LaLiga this campaign. Benzema has netted 30 goals in all competitions, 21 of them coming in the league. What's more amazing is that without his goals, Madrid would not be featuring in the Champions League next season as they would have been out of the top-four spot.
It is crystal clear that Benzema's impact is more than anyone in Real Madrid, at least in the 2018/19 season. Even if Madrid goes through a major overhaul in the summer, Benzema will surely stay as he has earned the trust of Zinedine Zidane and the board due to his stellar performances.
