As I said above, there is no way that the club is going to clear out most of its strike force. Are we really going to start the season with an injury prone player in his 30s and a youngster who's never started a PL game (and hasn't played as a striker when he has come on).
Just consider what a new striker means. They can come from three places:
The Premier League
A lower English division
Abroad
Players from abroad we know generally take several months to get used to English football (Gross took to it instantly but he was an exception). Lower division is a bit of a gamble - sometimes they work (Watkins at Villa), sometimes they don't (Adams at Southampton) and if they're from the PL they're either a flop or out of our price range.
I really can't see us starting a new season with an untried strike force. I'm sure we will sign a striker but we're going to keep most of our existing players.
As per the comment on the post, this only happens if we get a big offer for Maupay and he leaves. I think it is unlikely and he would be one of the "new" ones (alongside the genuinely new one we definitely need to sign).
