On Thursday, Daniel Davari and Dennis Mast both joined DSC Arminia Bielefeld, as they continue to strength ahead of their return to the 2. Bundesliga.
This follows on from Wolfgang Hesl's arrival and Michael Görlitz supposed signing, which should happen in the next few days.
Davari set for second spell in Germany
The Iran national team goalkeeper has signed a two-year deal in Bielefeld, and returns from Switzerland after just a one year absence from German football.
Davari was previously at Eintracht Braunschweig and, despite his heroics, was relegated from the Bundesliga with them in 2013/14 and left to join Grasshopper-Club Zürich.
However, his time with the Swiss side yielded just 10 league appearances - as he kept just one clean sheet and conceded 17 goals.
Davari had made Iran's provisional World Cup squad in the season he went down with Braunschweig.
"We have watched him for a long time," said sporting Samir Arabi. He added that Davari, "has already proven his skill set at Eintracht Braunschweig over a long period of time."
The stopper himself was "happy that the transfer worked out" and admitted he will be "proud to wear the jersey of Arminia Bielefeld in the future".
Mast looking to continue good form
"Dennis feels at home here, and we can imagine continuing to work with him," claimed Arabi recently - that soon became a reality.
Mast, who was on loan from Karlsruher SC, has been handed a three-year deal with the Westphalian club.
That comes after 35 games, five goals and four assists last season - a very impressive total for a central midfielder.
Arabi cited his "potential to develop" and the fact he is "a dynamic player" as two of Mast's key attributes.
The 23-year-old also spoke of his happiness of joining, especially with the "traditional club's fantastic fans".
