After all, Real Madrid wouldn't make a hasty decision if the transfer fee wasn't so reasonable for them for a player. And while waiting for the transfer fee to be lowered for Mbappe, Real Madrid can also monitor other players to get them if they really can't get Mbappe in the current transfer market. And which teams are starting to be interested in Mbappe apart from Real Madrid? Because a good player like Mbappe will usually be in greater demand by many teams if the price is not too high.
So, if you think about it, Psg will not sell Mbappe at a cheap price. Certainly PSG will set a high enough price in Mbappe release clause. So if Real Madrid doesn't move fast, it's very likely that another team will be in the hunt for mbappe in this season's transfer window. PSG has officially said that they don't want to lose money next season if Mbappe chooses to leave on a free transfer. Apart from that, Real Madrid also needs a quality center forward to replace the position left by Benzema.
Even in existing developments, it is reported that PSG and Real Madrid will meet to discuss Mbappe transfer because so far only Real Madrid has been very insistent on getting Mbappe. Well, looking at other teams it looks like they will be reluctant to spend big money to buy a player. But real madrid will most likely do so if their seriousness becomes a reality in the Mbappe transfer saga.
