In what sense? If Vlahovic is unavailable and tbh I don't trust Milik to be ready when called upon more often than most is Sancho or any other players we have currently (including Koop) going to fill that void upfront? Maybe I'm a but old school and was never an advocate of these false 9 systems
Milik had 8 or 9 goals as backup striker with limited playing time last season. Came in end of games and scored some needed last minute goals sometimes.
I want someone better but he was OK backup.
Backup striker shouldn't be a priority in a big upheaval transfer market. It's just a backup. While Sancho could be a key starting left winger if we get him.
If we can find an opportunity to move on Milik and find someone else yes do it. But it shouldn't be as urgent as a boost in quality LW. And Milik would be main backup, but even if I'm not fond of False 9s lack of presence in box, Yildiz and Nico G are capable to do that role in the minutes Kean used to get. And Mottas system thrives on false 9 role as we seen in Bologna so it's approach that's uniquely fit for it.
