It has been a good start to the week for TSG 1899 Hoffenheim fans, especially in terms of the midfield department.
On Monday, they announced the arrival of Kevin Vogt from 1. FC Köln. Just a day later and Eugen Polanski had committed his future to the club.
Hoffenheim have already announced that Niklas Süle will not be leaving this summer, and Andrej Kramaric's permanent signing from Leicester City.
Marco Terrazzino has been confirmed as a free transfer, and the club also completed a great piece of business by recruiting Benjamin Hübner.
More steel in the centre
Vogt arrives as a 24-year-old that is already well versed in Bundesliga play, having made over 100 combined appearances for the Billy Goats and FC Augsburg.
The tough-tackling midfield man has signed a deal through to 2020, and is part of the rebuilding process under Julian Nagelsmann.
A presence in the air as much as on the ground, Vogt will add youth to an ageing central midfield unit.
He spoke to the club website after the move, saying that he held "some very good discussions with Julian Nagelsmann and Alexander Rosen".
Vogt feels these "convinced" him that "his strengths" can add to the "success at the club". He added, "I am fully aware of this responsibility."
Polanski remaining with Hoffenheim
Veteran midfielder Eugen Polanski will also be at the club for a further year, as he signed a new deal to 2018.
The Pole has been with Hoffenheim since his move from 1. FSV Mainz 05 in January 2013, and has gone on to make over 100 appearances for the club.
“Julian has shown us clearly the direction we need to go in since taking over the team,” said Polanski, who was also speaking to the club website.
Being a part of the team as it develops further in the Bundesliga and being able to help out with my 12 years of football experience were important reasons for signing the extension.”
