I not sure that Goncalo Ramos will really be able to replace Mbappe and of course this would be an ambiguous decision if we really had high hopes for Goncalo Ramos to be able to fill the void and play as Mbappe replacement next season.
Indeed, I admit that Goncalo Ramos is also young and talented player, he has shown his contribution as an attacking player is also quite good, but this will not provide guarantee that he can and deserves to be called replacement for Mbappe.
It not just goals and assists to be able to replace Mbappe, there are several other factors that other players, including Goncalo Ramos, can't have, do you remember what Enrique said during the interview session asking about Mbappe replacement.
They have until now been too dependent on players so that when these players leave it seems as if the club will not be able to develop very well. But in the end we also have to remember that this is a match between clubs where 11 players all have a role not just relying on one player alone and with Mbappe gone now PSG must be able to prove that they are not that dependent on Mbappe even though we know that in the last few seasons Mbappe was the backbone of the team. The last few seasons Mbappe was the backbone of PSG but now they have to get up because Mbappe is gone and it's time to now change the scheme that always relies on Mbappe and replace it with a good cooperation game so that they are glimpsed not only because of Mbappe but PSG is glimpsed because of a club that plays well in terms of performance and cooperation.
By buying the right players in the right place, hopefully this team will become a strong team again and once again they will be on the field to succeed in the Champions League competition.
PSG need a suitable replacement for Mbappe. There is no doubt that Luis Enrique is a very experienced coach. Even so, it will be very difficult for PSG to perform consistently well without finding a suitable replacement for Mbappe. Because Mbappe was the most important player in PSG's squad. PSG can win the Ligue 1 title without Mbappe. But will not be able to do well in the Champions League.
PSG management should plan long term with Luis Enrique. Without long-term planning, PSG management will spend a lot of money every season, but not get the expected performance. PSG management is very rich, and they don't stingy on spending money. So Luis Enrique will probably be able to add as many players as he wants to the squad, as he is going to get a bigger fund from the management. Now we wait to see which player Luis Enrique is interested in signing as Mbappe's replacement.
