I'm sure the first priority for Leipzig was never taking Fabio Carvalho from Liverpool on a loan buy they wanted to buy this player because Fabio Carvalho is a young player and he can be a good investment for any team but Liverpool will never lose a player like Fabio Carvalho easily, Leipzig had to take him for the loan.
Leipzig itself must also be grateful because Liverpool are willing to provide Fabio Carvalho even though on loan. Because this can certainly help Leipzig to be better in the Bundesliga next season, because some Bundesliga fans still really want to see fierce competition in the Bundesliga with a fairly tight title race as happened last season and are also very much expected this season. the future could happen again to some teams who can make themselves more competitive next season.
Both of them benefit including players, Fabio Carvalho in Leipzig it will open up opportunities for him to be able to play longer than at Liverpool who might only be on the bench more often because Liverpool uses other midfielders more. Leipzig will benefit if this player can play well so that he can contribute to Leipzig next season, and Liverpool prefers to go on loan so that when this player is mature enough he will return to Liverpool as a main player to replace other players who have certainly experienced a decline.
Leipzig may have to wait because it is not impossible that in the next one or two seasons there will be a change from Liverpool, but if this player shines in this period there are two possibilities that he will return to Liverpool or will be sold at a high price and Leipzig must prepare these funds if they really want Fabio Carvalho.
