If everything *hasn't* been agreed in the Abraham deal we should be delaying the sale of the player that he's replacing until it is. If it hasn't been agreed, what's the new plan if it *doesn't* get agreed?
If Roma want Malen (and it seems that they do), then in the meantime they use one of the three first team strikers they've got already, or the new one that they signed at the same time as Malen.
In much the same way as we're not clearly not going to move on from Abraham for the sake of a day or two of delay, there's no reason to think that Roma would either.
