"There's a big game for us on Tuesday night against City and it will be a great test for us and the Sheffield United one. We'll see where we can get to, playing our football and see what points we get and end up. Today was important for the supporters and for the players.
"When you lose four in a row, irrespective of the circumstances and the opposition, it can weigh on your mind. It can dent your confidence and belief. I thought they handled it well today and at least that gives us a platform to tackle these last two games."
