I think the Mbappe issue is still unknown to the public because Real Madrid was looking for Mbappe last season and they failed to get him, and again this season they also do the same; they start looking for him to replace their weak position, which is the striking position, so I think if Mbappe's contract expires with Real Madrid this season, I don’t think he will renew it; he will want to go back to Real Madrid. The fact that Real Madrid really needs someone like Mbappe to replace their striking position made me think that they will do everything they can to get him during the transfer window.
Maybe it won't come true because Mbappe always gives false hope to Real Madrid. Mbappe might even extend his contract again, of course that could happen. Last season there was no offer from Real Madrid for Mbappe, it could be that Real Madrid have dropped Mbappe name from their target. I think Real Madrid would be better off tempting Martinez from Inter Milan because he also has quite good quality, even Mertinez is still young and can be prioritized for the long term.
It could even be that Ancelotti will bring in a player who is not well known and he will turn him into one of the best strikers. For this reason, Real Madrid management will not be in a hurry with well-known players who have high prices, they will look for players who have hidden talents for by Ancelotti to polish as strikers who are productive in scoring goals.
