The BVB official hinted at possible departures from the club for a a number of fringe names, insisting the team need better depth in order to fight for top honoursBorussia Dortmund sporting director Hans-Joachim Watzke has stated that the club will evaluate their current roster of players over the winter break and bring in quality squad reinforcements.
The 53-year-old is of the opinion that the club lacks enough quality in depth to face the challenge of three competitions and hinted that some of the fringe footballers at BVB might be shown the door.
"If we want to be in the first places of the table permanently, we have to improve in terms of the players 12 to 18," Watzke told Sport Bild.
"There are two games left. Afterwards we will analyse the first half of the season."
Croatian attacker Ivan Perisic has been rumoured to be at the top of the possible departures list after a public fall-out with coach Jurgen Klopp earlier this season.
Meanwhile, Basel defender Aleksandar Dragovic is reportedly on the radar of the German champions, meaning Brazilian Felipe Santana's spell with BVB might be coming to an end.
