Very interesting point . Wojciech makes so many costly mistakes and is always assured of his place as if we do not have a capable sub . Give Ospina a few chances and he will show us what he is made of . That will also improve Szczesny 's game .
It was of naive of wenger to throw Chambers in this game against his former team . There are always some nerves involved . Calum has had some bad spell lately . Wenger could have done it with Coquelin and Either Rosiky or Cazorla to protect the back 4 .
It is always risky to put two young and inexperienced players in a such a crucial position .
