#4 Rodrigo Moreno, Valencia

Valencia are currently 15th in the LaLiga and one of their biggest concern is the poor form of Rodrigo Moreno. Rodrigo scored 16 goals for Valencia last season and was one of the best strikers in European football.
He also made it to the Spain 2018 World Cup squad and made three substitute appearances. He was under the radar of top European clubs during the summer transfer window but Valencia did enough to retain their prized asset.
However, in his 15 LaLiga and UEFA Champions League appearances this season, Rodrigo Moreno has scored just one goal and assisted one more. The Spanish international hasn't scored a goal since August and has looked awfully out of form. He hasn't scored a goal in his last 14 appearances for Valencia and that has hurt them big this season.
