"You can't afford to make the mistakes that we made or not show the urgency to shut down that we needed to," said Omer Riza
"There were key errors in key areas - for the first goal losing the ball and not tracking runners. It was disappointing to give a goal away like that when before that there was really nothing in the game.
"Then the second goal was from a corner, which was disappointing, and their third one he had too much time and space to step in - you need to get close to stop shots.
"We were 3-0 down before you know it. Towards the end we scored two goals from the changes in the personnel, but it's all too late.
"There are 60 points to play for - still a long way to go in the season. We need to move onto the next game now, which is Watford. Of course, it's disappointing, because we came here wanting to win, but now we're looking forward to the Watford game.
"We need to win. We have to go out there and do all those little things properly, all the little moments. Show urgency to defend properly, not get broken down, to be resilient. To get on first and second balls, to get the ball down and play with quality rather than turn the ball over, and punish when we get the opportunity.
"We need to try and apply this in the very little space of time that we have. We'll work on a couple of things and talk about them, like we've done after the game today, to try and execute things better.
"A win can change everything. We'll go back to the drawing board, back to the training ground, and get ourselves ready."
Oxford's Gary Rowett:
"Przemy's is a wonderful strike, a goal worthy of winning any game.
"To get into a 3-0 position is terrific and of course what you don't then want to do it is allow the opposition to get back into it.
"But the main thing I take away from the game is winning the game, that's the most important thing. When you're in this position you want to find different ways to win the game."
