Reports suggest that Emre Can is wanted in Istanbul by both Galatasaray and Fenerbahce. We already talked about Galatasaray's interest in Can,
Pro: I'm firmly in the camp that would like to see Can go out on loan this season; however, there are two things that must occur before Can is allowed to leave. The first is that he must extend his contract. The second is that Bayern must not sell Luiz Gustavo. Can getting to play every day would be huge for his development at this stage in his career. While the Turkish league isn't nearly as good as the Bundesliga, playing with one of Turkey's biggest clubs and in Europe would be huge for him.
Con: It's the Turkish Superliga which isn't very good. It might do him good to spend a year training and playing under Pep before departing for playing time.
Diego Contento is being mentioned as a possibility of a move to Werder Bremen as a replacement for the injured Lukas Schmitz.
Pro: Diego is at a point in his career where he needs to prove that he either can or can't hack it as an everyday player in the top flight. He's under contract through 2016, so perhaps a loan would be better for this season? Give him a shot to prove that he can do it.
Con: After Alaba (Well... and Lahm), Contento is the best left back on the roster. While he is generally very up and down on the field, you never want to see a player that can contribute and fill-in leave the club.
A report in the notoriously reliable English paper The Sun (ha ha ha) suggests that Bayern are still interested in bringing David Luiz to Munich. It's being reported by The Telegraph that Bayern are prepping a €40 million bid for the Brazilian.
Pro: Daniel Van Buyten was quite overwhelmed in the DFL Supercup against Borussia Dortmund, and Jan Kirchhoff is inexperienced against elite competition. Holger Badstuber won't be available to play until at least January, and that's if everything goes according to plan for his rehabilitation. Plus, who knows if his knee will ever be the same. This would allow Javi Martinez to remain in the midfield and not be forced into a centerback role.
Con: The reports are unreliable, and that's a lot of money. The key thing here: The reports are unreliable. I would expect the club to deny this report completely at some point.
