Several weeks ago Barry was being hailed after some of his performances , and now he is suddenly our weak link ? Barry made a mistake , but it was sloppy play all round , he has just been assigned the blame. The midfield in general , when we play top sides will be a weak link , purely because during a game , the midfield two are either forward or they are at the back . When we go forward both Barry and Yaya go at the same time , there is then nobody holding if we lose possesion , like against Napoli . Then if both midfielders come deep , due to the fact that Aguero and Dzeko play more or less alongside each other , there is nobody in the hole . If there was somebody in that attacking midfield role pressure can then be applied to the centre halves more and the sooner they make a mistake and the sooner we get the ball back. Also both central midfield players don't have to go forward. Against teams like Wigan , it is ok to go all out attack , especially at home . But at home against strong teams aswell as away , we would have to put three in the middle , with two of them holding and one central attacking midfielder as opposed to 4-4-2. Currently the system is working well , we are scoring bucket loads and conceding very little , but the Napoli goal on Wednesday outlines the problem with the midfield , against teams with the quality to hurt us.
