Last few seasons Taylor has only worked with a core 11/12/13 in training. Subs and fringe players were left to work with other coaching staff (and Houghton led some training). It was very much a case of if your not in his 11, you felt like you were cast aside and you were only going to get in/get back in if an injury or suspension happened.
He's also an "I speak you listen" manager and there wasn't ever any opportunity to offer your opinion or speak about your concerns etc.... not always a bad thing but also not very good for player management at times, especially when players go away with international teams and are offered different advice and told they need to play more which causes conflict when back with you club side.
I'll add that this was the case in previous seasons and I no longer have the sources at the club to clarify if this is still the case, there have also been a number of backroom changes so this could now be different. I suppose I'll have to give Taylor the benefit of doubt after masterminding one of the best performances and results in the clubs history against Barcelona.
