In hindsight, it wasnt the worst decision to keep him, as he was the most consistent player for Dortmund 1st half of the season and elementary for reaching round of last 16.
If Dortmund would have found a suitable replacement, then they maybe would have changed their mind..the market was crazy inflated though and their pride also played a role I guess. They tried everything to sell him abroad, but he simple refused and then time ran out and they needed to make a decision.
There r so many talents in Germany, that it ll be easy for the Klopp/Zorc/Watzke combo to find proper replacements. I m sure Volland tops their list, as he would be perfect and they ll add some more talents maybe Ginter, Mitrovic. The income of Dortmund is rising so fast so the money is definitely there, they just have to increase their wage payments to finally offer adequate contracts..4-5m gross is a joke for such coveted players they have to up it to 7-8 in the near future.
