With Arsenal having problems of late in defence while Koscielny had been injured, the club are now facing pressure in trying to tie the player down to a new contract.
The Club are facing pressure from German Giants Bayern Munich, as well as French giants PSG and money spending Monaco. Arsenal cannot afford to lose another big name defender as Sagna seems to be on his way out.
Koscielny has been one of Arsenal's star players this season. Along with Per Mertesacker, the two have had one of the best centre back pairing results in the League. Along with standout performances, Koscielny has played with heart and passion for the club. To lose a player of his stature would result in great consequences and could put Arsenal in a real sticky situation come the transfer window.
