It is well known that Arsenal have sent their trusted scouts to assess the Polish international playing for Seville against Barcelona in their recent UEFA Super Cup final in Georgia.
He is first and foremost a very competent defensive midfielder who could provide equal competition and cover for Coquelin.
But for those who watched the game would have noticed that he played for 80 minutes as a centre back due to the unavailability of the first choice for that position.
Arsene apparently would value this dual role that the 25 year old could play just as Sagna or indeed Song used to provide.
