The downside is in buying him back.
Too expensive, bad physique and worse is yet to come in terms of fitness due to age and playing style.
We could bear another loan deal but he has not been performing at all like a 20m a year player that he's costing us... More like a 3m at best this season. On top of having Correa being pretty much useless and Dzeko not getting any younger, our situation up front is not ideal.
The irony is that both Lukaku and Dzeko have ended the season with decent numbers, something like 15 goals each.
