Dortmund have an interest in Luis Suarez after learning about Haller's medical condition. I hope that Haller can recover in as short time as possible also. Luis Suarez has been free agent for some time and he has been rumoured with some MLS and Argentina league teams also. If Dortmund make an official offer to him I think that his choice can be them. We haven't ever seen him playing in the Bundesliga so far therefore I'm curious how good he would play there.
Former Salzburg striker Karim Adeyemi could be an alternative if Haller is not fully ready for the Bundesliga match, and there are names like Moukoko and Reus. I don't think Suarez will be introduced as a new Dortmund player because I see the deals with Adeyemi and Haller recently quite appropriate as a form of change after official releasing Erling Haaland to Man City.
By the way I just see Matthijs de Ligt join Bayern Munich, the right choice to replace Niklas Sule
Adeyemi is also a good thinking yes. His performance at his former team was really impressive. He is too young maybe but it was the same for Haaland too. It is up to how much Adeyemi will perform to be a regular in their starting eleven. If he doesn't have a hard time adapting to the league then we can most probably see him there. Moukoko is still 17 years old so I don't know if they would prefer him too much. This might be the reason why they are said to be after Suarez.
I believe Karim Adeyemi is a very talented player and can become the best forward in Bundesliga. But now he is only 20 years old, which means
it still takes time to become a player that Dortmund can rely on. And not the right player to replace Haller, because Adeyemi is inexperienced and
also not ready to be given a heavy burden as Dortmund's main striker. I think Adeyemi still needs to be given a few more years to find his best
potential. So still Dortmund did have to bring in new players again to be able to replace Haller's position, because it can't just expect Marco Reus
to be able to play the full season, Dortmund still need an experienced striker. For now maybe bringing in Luis Suarez whose contract runs out
at Atletico could be the best solution that Dortmund can take.
