It does feel that way. Every manager rigidly plays the same system despite the results. Just like with Baz who despite being statistically terrible, remains in goal. Surely all the managers we've appointed don't have just ONE idea about how to play football.
Even if you kept appointing like-minded managers, one of then would eventually buck the trend.
A few games ago I hoped Tonda might stand up and find is own voice. Unfortunately that now looks impossible.
If we continue as we are I can't see him lasting after the Pompey game. Simply because fan sentiment and anger toward the club at that point will intensify and the owners will be forced to act as they eventually did under RM.
