According to Transfermarkt, the likes of Fulham, Schalke, Hertha and Mainz are keen on the 25-year-old as well.
Newcastle need to sign a left-back at the end of this season and Collins could prove to be a decent addition. He has done well in the Bundesliga with Paderborn.
Collins has been directly involved in three goals so far this season and he would improve Newcastle’s attacking play as well.
Furthermore, his contract expires in 2021 and he should be available for a reasonable price.
It will be interesting to see if Newcastle submit an offer for him this summer.
