The problem is, do you throw promising youngsters in a bear pit to see if the can turn the season round, or do you rely on proven players to get their acts together and turn the season round?
If getting the sack was not the first option available you, then you try the younger players in games to test their potential, if getting sacked is the first option you stick with the experienced players and play around with formations and tactics
If Javi was guaranteed next season regardless then the option of blooding younger players would be good for the fans and long term for the club
If he is not guranteed next season his ONLY option is to stick with the current players and hope he can get a better second half to the season
The answer is solely down to our owner, if failure to get promoted results in the sack, no youngsters will be fully blooded, just tooooooo risky
