There is something wrong with the goalkeeper perhaps. But if the defence keeps the opposition to just 2 or 3 chances a game. Then its playing very well. And possession wise we ate around the same as every other top 6 team I think we and Arsenal are 1 %rage point better than Pool and Chelsea and 2 over United and Spurs. In other words, its not just possession that is causing the lack of opportunities. The other top 6 teams have majority possession too. Yet they give up more shots. But save more.if the opposition score consistently from the only chance they have (or two chances they every have) then there is something wrong with the defenders and goalkeeper when it comes to defending.....we need defenders and gk who are not only good at the build up and maintaining possession but who are also good at the basic art of defending.
I don't disagree on the putting our chances away more bit either but you need to get both right
Statistically, its our goalkeeping that is inferior, not our defending per see.
