There are levels between Gravenberch and Phillips, both talent and value for money wise. That's where your scouts earn their living, either sign Phillips when he's still in the Championship or get a French version. Also it's not like Villa's money hasn't lured players already who are normally considered above their level ie Bailey, Coutinho etc
Anyway one very good signing they made which I'd take off their hands is McGinn. He's just a year older and while a very different type of CM a better player than Phillips, shouldn't cost nearly as much either if we can unsettle him. Not sure he'd start for us but he'd be great as a rotational option
