It´ll be interesting to see what happens this summer @Bayern. They said often that there won´t be much activity. They already announced the transfers for Niklas Süle(CB, 21) and Sebastian Rudy (DM/RB depth, 27) from Hoffenheim.
Rudy will be some kind of a Philipp Lahm. Versatile, smart, technically skilled, small and skinny. Süle will be the 3rd CB option behind Hummels and Boateng. The guy is a huge bull and can score on set pieces. If he improves his passing, he will can overtake both of them in the next two years.
Look at the lineup in the 2nd leg vs. Real:
Neuer (31) - Lahm (33), Boateng (28), Hummels (28), Alaba (24) - Vidal (29), Alonso (35) - Robben (33), Thiago (26), Ribery (34) - Lewandowski (28) // Subs: Douglas Costa (26), Müller (27), Kimmich (22); Bench: Ulreich (28), Bernat (24), Rafinha (31), Coman (20).
Look at the younger guys, 25 or younger (which isn´t even young) and I include Renato Sanches here, the only other guy 25 or younger with regular match time:
(BL matches / BL starts / CL matches / CL starts / DFB CUP matches / DFB cup starts)
Total: 29 BL matches - 10 CL matches - 4 DFB cup matches --> 43 matches
Alaba: 27 BL / 24 BLS /// 9 CL / 9 CLS /// 4 Cup / 3 Cup S --> 40 matches, 36 starts
Kimmich: 22 BL / 12 BLS /// 8 CL / 3 CLS /// 4 Cup / 2 Cup S --> 34 matches, 17 starts
Bernat: 13 BL / 9 BLS /// 4 CL / 2 CLS /// 3 Cup / 2 Cup S --> 20 matches, 13 starts
Coman: 16 BL / 8 BLS /// 2 CL / 0 CLS /// 3 Cup / 1 Cup S --> 21 matches, 9 starts
Sanches: 15 BL / 5 BLS /// 6 CL / 2 CLS /// 2 Cup / 1 Cup S ---> 23 matches, 8 starts
I don´t know if Bayern has to buy some new players besides Süle and Rudy (both german national team players). Ancelotti doesn´t play the youngsters. Alaba is still young, it´s insane that he´s 24, but has already seen it all with Bayern and you can´t count him as a youngster.
Kimmich also played in Germany´s Euro 16, which was a great experience, but maybe caused some physical problems for him this season. Same goes for the other young guys Coman and Sanches, who both played in the Euro final and can´t get regular starts for Bayern (because of Ribery and Robben having their 11th spring). I could also include Douglas Costa, who may not be loved at Bayern and often is quoted in the media while talking about leaving Bayern. I mean someone has to play on the wings and Ribery and Robben will be gone in 1-2 seasons.
Alonso will be gone in DM, so maybe Sanches gets it together. One of Kimmich or Rudy could play as a RB or in DM.
Just to add, look at what Pep did with some of those:
Coman played in 23 BL matches and started 20 a year earlier (although both Ribery and Robben were injured quite often). Kimmich played in 23 and started 15 (about the same). Bernat played in 16 and started 13, while he was out with an injury for a long time in between the season.
Pep just played them, trusted and developped them. Ancelotti is doing his thing with his oldies and I think it showed vs. Real, where he had to play some unfit players or guys who just came back from injuries.
I´m curious what will happen, as "The Brow" likely won´t be happy with Lahm and Xabi going out and two young guys stepping in. If they get this done, they will be okay probably. The next construction site will be the winger position (esp. if Douglas Costa won´t stay) and DM doesn´t look like a strength if Thiago moves to the No.10 position and there´s only Vidal and Rudy, with Kimmich and Sanches, who don´t offer much experience.
