If we get Antony and Gakpo go,he does not suit Ten Hags playing style,thanks for the memories Ronaldo.
I think Antony would suit him well. Antony doesn't score many goals, tends to play far from goal and on the touchline, and is a good crosser. Gapko less so, for sure, as he's basically a less explosive, tidier Rashford who would want to play 1-2s with Martial.
Best case scenario would probably be he takes a pay cut and leaves and we sign a physical, younger #9 with re-sale value to backup Martial who gets a year to convince Ten Hag one way or the other. If Martial is good and we keep him and sign an expensive #9 next summer then we move this signing on for a 5-10M loss.
It's too bad because Cristiano is the right fit to fight with Martial (who is much better at linking play but will probably go through a slump at some point) and be a Chicharito type scoring goals off the bench at this point in his career, but he doesn't seem to be eager to accept that role, even though it's probably best for the club AND for Portugal, where he should be their backup 9 in a Leao-Jota-Silva frontline that would have lots of energy and allow them to get Vitinha (who was phenomenal the other day against Lille and seems to be starting for PSG), a runner like Matheus Nunes or Renato Sanches and either Ruben Neves or one of their giant, boring DMs into a far more balanced midfield, especially since they have the best set of attacking fullbacks in the world in Nuno Mendes and Cancelo who could attack more freely with a quality midfield like that.
