Asked how he will keep the concentration of his players on the league campaign while preparations for another quarter-final begin, Harris said: “We don’t lose that focus in the changing room.
“You try and pick the players that can adapt from one day to the next, it’s trying to keep the fan-base settled – the League is important.
“I think we know how hard it is to stay in the Championship. We know how hard the fight is we are having at the moment. But that is six wins and three draws and two defeats in 11 games. So we know we have got momentum and results like today just carry that into Wednesday against Derby County.”
