Maybe Im wrong but I will say Neymar.
The guy is just a different level of low now without the system of Barcelona helping him.
When you consider how Suarez has done this season when leaving Barcelona (and where Barcelona are without him) - then maybe Suarez was the second best forward at Barcelona.
* Also shows that amazing players can potentially be found out when moving to different leagues and different clubs; (ie Neymar at PSG or Ronaldo at Juventus) this is why players who stick to one league or a single club maybe looked upon as taking a slightly easier career route by some people (but not all people).
How has Neymar been found out in Ligue 1 or for PSG? He has been generally excellent outside of injuries.
