Your words are irrelevant, you can't predict the future, so your statement is completely baseless. And he is a proper RB, and very good signing no matter how much you try to put a negative spin on it.
Dalot was a cheap signing, he was certainly not an academy signing, which means he was bought for the first team. It does not matter if it was an investment or not, he was cheap and brought in to play RB, but has been injured too much so has not made any progress. Which just goes to show that potential means feck all, and performances matter. AWB has been a very good signing overall, and saying he is bad because he might be replaced in the future based on nothing more than your guesswork about the future is about the most nonsensical crap I have seen posted here.
