Midfielder Michael O’Connor conceded Port Vale were simply not good enough in their draw with Maidenhead United.
The Valiants had a goal lead heading into extra time at the end of the tie only for James Mulley to bag a last-gasp equaliser for the visitors.
Rob Page’s side did have the chances to put the game to bed but couldn’t take them and O’Connor admitted the performance was nowhere near up to scratch.
“I thought it was shocking from start to end,” he said. “We had one or two patches where we looked lively but overall it wasn’t good enough.
“Even if we’d have won one-nil I don’t think it was good enough but it’s the FA Cup, you saw yesterday there were shocks.
“Crewe got beat by Eastleigh, Barnsley getting beat by Altrincham so the only good thing about today is we’re still in the FA Cup.”
He added: “They came and put up a good fight but I thought we should have been out of sight before they got their equaliser.
“We didn’t take our chances and it just wasn’t good enough.”
Vale will now travel to Maidenhead next week for the replay but face Barnsley in Sky Bet League One prior to that.
O’Connor believes it will take hard graft in order to get the FA Cup result out of the system at Oakwell, saying: “We just have to get back on the pitch and work hard.
“It’ll be a different game against Barnsley next week, it’ll be a tough away game. Our away performances haven’t been good enough this year.
“So we’ll get in tomorrow, have a little chat about today. It wasn’t good enough but we want to put it to bed as soon as possible.”
