i wouldnt take him back now, he needs the field experience, but i wouldnt let him go either.
He seemed to be the most promising finisher of his crop. And they tend to be hard to find and considerably expensive, the more we keep him, the more money we will make out of him, either by saving us the hussle of spending big for a finisher, or buy raising his value and create more income.
He will probably be included in the Ogbonna deal, but hopefully we will keep a part of his contract and the abilitity to buy it back in the future.
