Lacazette is the typical of pure centre striker and although Real Madrid has several players for front lines but basically they don't have the players who can be played on CF position and last season Real Madrid has Joselu but unfortunately he was sell to Qatar club and i think Real Madrid has capability to bought younger striker rather than Lacazette and i don't think this rumour would be happened and i know currently Lyon has facing serious financial problem and most likely they will going to sell some players this January but i am not sure Lacazette transfer will help Lyon to solved their financial condition because according to Lacazette market price his value is only 5 million so i personally didn't think this rumour happened
Real Madrid sold Joselu because Ancelotti was sure Mbappe will be fine to play in center forward position. But, since the plan wasn't working like he expected, Ancelotti choose to bring a pure center forward. Lacazette, who has low market value and play in Lyon, will high likely move to Real Madrid.
I'm sure if Real Madrid willing to pay 10 Million Euros, Lyon will accept the offer.
Everyone believes Mbappe will perform well when he joins Real Madrid, which is why Ancelotti opted to let Joselu depart, but Mbappe has not performed well for Real Madrid. And if Ancelotti really wants to bring Lacazette to Madrid, it would be a fantastic move because he is a good player who is performing well at Lyon. But that story has yet to be confirmed because Real Madrid does not require any forwards right now. Instead, they want to focus on left back because that is what the squad now lacks, so Ancelotti will focus on defenders because I do not believe Vini Jr, Mbappe, or Rodrygo will be replaced. Because they are crucial players and they are in a better shap is just that Mbappe as not master the striking role is playing in Real Madrid, but am sure gradually he will learn it and become perfect because they said practices make perfect. So I still believe with Mbappe that he will turn up soon, since he didn't move the the international break and is training am sure he will be mastering the striking small small because in the pitch he can't stay in is positions.
