I'm happy we've signed Warner as he is definetly experienced, whether he is any good only time will tell! As for Kay, I have some doubts over his attitude as he turned down an extended loan deal at Gateshead because he would prefer to play reserve team football - that kind of attitude stinks!

We do need a right back due to injuries though so hopefully he will do ok, it's a shame we can't get Shotton though. As for McChrystal, I'm happy we've now got four permanent centre backs but Parry's Irish exports have been pretty useless so far, so hopefully McChrystal will buck the trend.
I think Broomes got a three match ban as it was a straight red, I think Wooton has also gone back to Manchester United - but from what I've seen of him he isn't much of a loss.
If Blanchard is out for 6 weeks that is a major blow as he's been pretty consistent this season, and can play in several positions.
