A couple of things to add, both are reasonable ages to, I think both just turned 26, so in theory some scope for modest improvement.
Also worth noting that they have scored goals in the PL. I count that as a currency higher than other leagues, partially as it's a harder league, partially as it does take time to adapt.
Both can play across the front too, so can dovetail with Dominic, but also replace him if needed.
They are a kind of low risk, very modest reward signing, that perhaps the club feels it needs to survive. Let's put it this way, if they were to come in, and get 15 goals between them, that will probably keep us up, get us to next summer where there is more FFP flexibility and allow us to be more ambitious.
The other point I'd make, is that if you had those 2 in, it may allow us to be a little more ambitious with a 3rd player, and take more risk.
I suspect it will only be one, but they are ok. I'm surprised they are both being let go, particularly Adam's at Southampton. Im not sure I'd pay 15m for either, especially with Maupay in his final year. Hes a bad finisher, but actually a very good link striker.
