You're forgetting Keane as far as defenders are concerned.
Coutts , for me, is a long term replacement for McKenna and a standby for him. I'm not too keen on Anderson but I will not say he will be bad for us because he obviously has talent and it's a question of whether Steve Bruce can get him back to where he should be.
I still have this niggle in my mind. Unlike most, I really like the idea of 4-2-3-1 as I think it will result in us controlling games far better than a 4-4-2. However, I just cannot see Fryatt fitting into that as, with last season as evidence, he is not suited to the lone striker role (16 goals is good but it won't usually get you promoted if that is the top scorers tally). At the same time if we use Fryatt as an impact player off the bench, I think he'll be off and also it is surely still a doubt as to whether Heskey can carry off the lone striker role for a whole season.
So, if we say Bruce intends to play 442, where does Koren play? In my view he cannot play in the middle of a 442 with a winger each side as he is not strong enough to do enough when we don't have the ball. If we play him wide, he isn't anywhere near as effective and he doesn't like playing there either.
I think there are a whole lot of questions regarding the squad and formations still to be answered. I hope Bruce comes up with the right answers!
