The way you're framing this quote is completely wrong. He didn't throw Poch under the bus at all. He was talking purely about the players.
''I can see why the manager is frustrated because he’s been here for six years now and we’re still making similar mistakes to the ones we were in his first year. We’ve got to find a way to get around it, improve and get better.''
1 mistake we make is our inability to clear the ball out of defence and the insistence on playing it out 'tippy tappy'. Sometimes you need to just welly it away and concentrate on winning the ball back farther up the field. Clearly that has to be an instruction from the coach.
