I know that I am often regarded as a lone voice but I would sooner CH play an experienced player in slightly different role ie just in front of the back 4.rather than an untried inexperienced player who, had he been near to being ready would have been on the bench by now.
I think that apart from not winning headers to lay the ball off Andone looks better than GM playing away as he is more mobile. Tough call. I know . I think that I would also drop a wide man and bolster up the midfield with an extra man when all are fit and available.
I would suggest that the number of games that he played well in you could count on 1 hand but I dont wish to get involved in an argument about him as I believe that we have bigger problems until Gross Propper and Stephens are all back playing to their best level and together.
