IMO Brady needs to persist with Etete as the lone striker in a 4-2-3-1.
As you say, the ability and physical attributes are definitely there but he needs to work on the tactical and psychological side of the game. He needs to learn how to time his runs and when to hold it up to relieve pressure (and not give it away to allow dangerous counter-attacks!).
Perhaps most importantly he has to learn to accept and transcend the standard rough treatment dished out by L2 clogger centre backs and to use his 6'6 inch frame to dominate them.
Hopefully Rico is doing a lot of work on the training ground with him, but he will need a run of games to properly master the lone frontman role and we, and Brady, will need to be patient.
My worry is that Brady will drop Etete as a knee-jerk reaction and bring Rose back because he's more of a 'safe pair of hands' in terms of hold-up play. This would be a massive mistake IMO because we looked so much better in a 4-2-3-1 and probably created more chances than we have in any other game all season. Rose IMO doesn't have the physical attributes to play as a lone frontman and should be used off the bench as a second striker option if we need to change it and go 4-4-2.
As I've said earlier in the thread, I'd put BAS just above Kabamba in the pecking order and would rather see him as an option coming off the bench. Not much in it but I would say that Kabamba has had enough chances and has made 0 impact.
Looking ahead to January, I would be looking to ship at least one of the misfiring strikers out and to bring in an experienced centre forward who can lead the line and offer genuine competition for places.
I think he's likely to bring Rose back for the next match as we are playing Mansfield, his old club, and that often works. I would play Etete though.
