Agree with the above... Kovac has been a great back up player so much so that according to capello his the man for our long ball system. On a serious matter yeah I would keep him.
Why we need camo out, is simply down to personal hatred and nothing more. Getting rid of chiellini and bringing another left back doesnt make sense they are both young, its a waste of time, resources and most of all faith in a player by getting rid of him. Now that his settled in, to remove him would be a step backwards. Viera has shown his quality against siena and the first part of the season, seriously I wont get rid of him. At the same time if we really are serious in bringing Yaya, then we can by leaving Viera where he is and removing Gianni and Blasi. However with us bringing zanetti then I dont see the point of spending more emphasis on a defensive midfield position. Ronaldos a joke.. enough said about him.
