We still have Toni and Klose who are both quite similar to Gomez in some ways, and obviously, Gomez is much younger. I would rather bring him in next season. He cant be more expensive, as his contract will be running out in 2010, so the price would prob be cheaper.
I would rather prefer Bayern bringing in someone like Aguerro, who has better ball control and ability to score from dribbling past two defenders. Bayern doesnt have this type of striker now.
I think Bayern would definitely bring in a midfielder to replace Ze Roberto next season and hopefully, they will look at their central defence options as well.
