If he can bring Gosens, Union Berlin will have made a really good transfer. The German player adapts to the Bundesliga in a short time. He left behind a successful season at Inter. He played in UCL in 11 matches and it was a great experience for him. Union Berlin should definitely bring him to the team.
That would really be a magnificent coup from Union Berlin. With Robin Gosens they would get a good player. Robin is only 22 years old and if he should go from Inter to Union Berlin, it shows that Union Berlin has developed into a serious club in a very short time.
But his market value is about 15-20 million euros and that would be a very huge sum for Union Berlin.
