I've watched Ighalo play and his worse than Rondon who I've also seen. Bakambu has similar stats with Ighalo in China but he also scored goals in La Liga till his last season there unlike Ighalo
So, you’ve watched Ighalo regularly in China? You think that is a good league to judge quality on? In other posts you say Rondon is a proven PL striker, but his goal scoring record in the PL is nowhere close to Ighalo, who has seasons of 15 and 20 goals for Watford. Rondon got max of 11.
Rondon: PL record:goal every 309minute. China record: goal every 151 minute.
Ighalo: PL record: goal every 177 minute. China record: goal every 133 minute.
You may argue that Rondon is better in general play, but they are very different player types, Ighalo more of a poacher while Rondon is more like a target man. So comparing them is kind of like comparing apples and oranges.
i haven’t seen any at all of Bakambu, so not gonna argue there, other than point out that its a player without PL experience. That itself is a big risk of a flop.
I’m not saying Ighalo will succeed or flop, but in my opinion, between the alternatives you provide, Ighalo is the better alternative.
