Need a good striker (Start of 2nd Season)

My current team: Man United, 2nd Season.
I won the quadruple last season (BPL, Champions League, FA Cup and Capital One Cup)
I didn't lose the whole season in all competitions.

But don't have a strong striker thats always fit. Hernandez scored 27 goals, Welbeck 11 (sold) but RVP only scored 9 and is being a waste of space and useless. (in all Comps)

I got 50m left of the summer transfer money left and wanna buy a strong striker, I wanna only spend 30-35m of that on a striker and maybe trade RVP as well as a part of a deal.

Either up coming talent and good already or already established. Also any other good players?

Anyone got suggestions?

Shola Ameobi. Wonderkid!

Nah, seriously though, maybe Lukaku or Lewandowski.

Falcao, Damiao, Cavani, Rondon.

Rodrigo from Benfica. His shooting is top class, he is very fast + good fitness, and he is amazing on the ball. He also has high flair and composure, and he is only 21-22 years old. He is a top, top player for any team.

Edinson Cavani you wont go wrong but RVP can get you the goals if you play him on the right side as a deep lying forward ...trust me
