Dortmund really needs to have a reliable striker. Honestly, Louis Suarez is not a player who can be relied upon, especially when he is 35 years old. And he also did not have a very successful season with Atlético de Madrid in the last season. Haller was going to be the main striker of Dortmund but right now it does not feel like he is going to be available very soon. Louis Suarez is a viable option but it would be preferable if Dortmund did not just rely on Louis Suarez to do all the scoring. Particularly if they want to improve on the results they got last season. He did not have success last season in my opinion but I know a lot of other people are more likely to disagree.
Yes, totally agree, due to his age he is already starting to slow down in his game. Also, have there been any rumours of his transfer? To some extent such a player would help the team anyway, but they should understand that if they sign him, it will be for one or maximum two seasons, because only he knows when Suarez will finish his career
