Arsenal were linked with RB Leipzig defender Lukas Klostermann two years ago but no deal materialised. This summer Klostermann has surfaced on Arsenal’s radar as reports suggests Arsenal are ready to revive their interest with new manager Unai Emery looking to strengthen his defence this summer. Arsenal are also on the verge of signing Sokratis Papastathopoulos from Borussia Dortmund after having just signed veteran Swiss defender Stephan Lichtsteiner on a free transfer from Juventus on Tuesday.
