The transfer window for RB Leipzig, one of the most successful clubs in German football, is fast approaching. With new manager Frank Rijkaard set to take over from the outgoing Thomas Tuchel, there are already rumors swirling about his potential signings.

According to reports, the Dutchman has his eye on a number of players who could help him build a strong squad ahead of next season. One player that has been linked with a move to Leipzig is Real Madrid midfielder Casemiro, who has been out of contract at the Spanish club since last summer.

Another player that has been rumored to be on RB Leipzig's radar is Manchester City winger Raheem Sterling. The Englishman has been heavily linked with a move away from the Etihad Stadium after falling out of favour under Pep Guardiola.

In addition to these two players, RB Leipzig is also expected to make a bid for Barcelona forward Lionel Messi. The Argentine superstar has been linked with a move away from Camp Nou for some time now, but it remains to be seen whether or not he will join Leipzig in January.

Overall, the 2026 transfer window is shaping up to be a busy one for RB Leipzig. With new management and financial stability coming into play, the club is likely to make significant moves to strengthen its squad ahead of the new season.
