Oxford United caretaker manager Mickey Lewis admitted he was "fuming" after his side conceded an injury-time equaliser at Morecambe.
The dropping of two points saw the U's slip out of the League Two automatic promotion places.
Lewis told BBC Radio Oxford: "I'm fuming. I'm not happy at all, I thought we needed to be better on the ball and should have got another goal.
"I think I'm quite a nice guy, but the last 20 minutes wasn't good enough."
Oxford had taken an early lead when David Connolly's deflected shot beat goalkeeper Barry Roche, only for Morecambe defender Robbie Threlfall to poke home from close range two minutes into added time.
"Morecambe were coming at us but we should have got another goal on the break," said Lewis.
"In the last 20 minutes we didn't win enough headers, we missed challenges all over the park, and I'm really disappointed because I think we should have got three points.
"If we'd been a little bit better on the ball we would have gone on and got a second. When we broke out we weren't good enough, our quality didn't show through.
"I didn't think it was a great ball in for their goal and I think we should have cleared it.
"We've had a few words in the dressing room but what's said in there stays in there, and we move on."
