I agreed about this as Federico Valverde is here for long time as this is his boyhood love club, and he will never think to leave right now, but officially we have second big from the Liverpool which is having worth of £77m with most chances this is also going to be rejected but good thing they are trying this which is also worth to try for the player like Federico Valverde.
Valverde was grown up by Real Madrid and he is one of their best young midfielders. Casemiro was sold, Modric is too old and likely will have last one to two seasons with Real Madrid, Kroos is already old enough and Valverde is one of best midfielders for Real Madrid future. He loves the club, play well and Real Madrid will send him to another club. Except if Real Madrid buy a very expensive midfielder and Valverde loses his position in the squad then will feel unhappy, a transfer might occur.
So far, no signal for such things in Real Madrid and he will stay in the club. Real Madrid will not sell him just to buy Mbappe in my opinion.
All speculation will arise before there is certainty about the fate of Kylian Mbappe, Real Madrid will do a lot of things to bring in this player, including releasing other players if it has to be done, but of course they will not make decisions carelessly, because every player has an important role, especially if these players are core players, making the wrong decision will only result in losses and every club has experienced a failure in purchasing players, and Real Madrid has experienced this buying expensive players but not having any contribution to the club like what happened to Eden Hazard, yeah both players are different people but Real Madrid will of course be very careful especially they have spent quite a lot of money by buying Jude Belligham, because they will not only spend a lot of money to bring in this striker but also pay his salary while playing at this club.
