I think he is right about that really. We didn't lose because of our choice of keeper. Ospina has been reliable by all accounts and if the outfield players had done their jobs, we wouldn't have been 1-0 down or shipped another goal straight after scoring one. Ospina was comically responsible for the second and of course you would expect our first choice keeper to play in a 'must win game' but our second choice done well enough last season, he isn't exactly an early-days Fabianski, disaster waiting to happen. Look at Cech against West Ham, no-one expected that sort of fuck up from a world class keeper. The bigger story and problem of our CL is poor defensive, stale midfield and limp attack. Which of course are Wenger's responsibility and he should be hammered for that, instead of concentrating on a keeper responsible for one of the three goals.
