Luis Suarez until now have no clubs although he has linked to several clubs from England and Spain but he hasn't decided which clubs will be his destination and currently rumours is his agent has been offering him to Dortmund and Dortmund has confirmed this news that they will considering to get Suarez but Dortmund have to see Haller health condition first and if Haller cannot play for long term period then Dortmund probably will get him and they have a plan will give Suarez short term contract
I am very surprised to see no club knocks Suarez door and bring him in their club. Despite of his age, Suarez is still a good striker and if a club is doubt about his ability to play as a main striker, they can buy and use him as a second striker, alternative for their main striker.
Dortmund can be an option for Suarez together with Bayern. I think Bayern and Dortmund are good options for Suarez in last years of his career if he wants to play in Europe. If he does not want to play with high pressure, MLS will be a next option.
Bundesliga would be a very good option for Luis Suarez. The defenders play very hard in Italy Serie A, the matches are played at a very high tempo in the English Premier League, these two leagues may be difficult for him because he is now 35 years old. I think Germany Bundesliga selection would be the best choice for him... By the way, I really felt sorry for Sebastien Haller. He is suffering from a critical illness. I know someone who passed away from this ailment. I hope his status isn't too serious.
Bayern just lost Lewandowski and they will filter the market to find another striker. Even they bought Mane weeks ago, the transfer of Lewandowski to Barcelona will force them to buy another striker. If they don't want to spend big transfer cost and very high salary for Ronaldo, Suarez is a better option.
Suarez can score from 15 to 20 goals in a season and I think this combines with Mane will be enough for Bayern attacking system. Suarez and Mane can replace Lewandowski as a new goal resource for Bayern.
