Crewe manager Steve Davis admitted his young side was naive after seeing them held to a fourth straight draw, 1-1 at home to Leyton Orient.
Teenage debutant Ryan Colclough went close to stealing a late victory for Crewe as he was involved three times in penalty-box drama in the closing minutes.
"Maybe we are a bit too young at the moment. I might have to dip into the transfer [loan market] as the squad is a little threadbare," Davis said. "But Ryan has got lots of ability as he showed and hopefully he can build on that. He did well in pre-season and in our under-21 league games he's been one of our star performers."
Matt Tootle fired the Railwaymen into an early lead with only his second goal for the club, but Martin Rowlands smashed a superb first-half equaliser and the Londoners will be aggrieved they did not make their dominance pay in the second period.
Russell Slade's Os have enjoyed an unspectacular, but steady start to the season and field a line-up bristling in experience with the likes of Rowlands, Kevin Lisbie, Dean Cox and former Port Vale midfielder Anthony Griffith.
Without the influential Byron Moore, who had been left out on compassionate grounds, Crewe struggled to offer a supply line for young Clayton and Ajay Leitch-Smith.
Anthony Griffith saw red in stoppage time after a late lunge on Luke Murphy earned him his second booking.
Orient boss Slade had no complaints about Griffith's red card, saying: "They were both bookings. He was a bit silly for the second one."
He added: "It was a very open game from first to last and both teams were trying to win it.
"Crewe started the better - they're the best starts in the league as they showed at Stevenage. But we had a fantastic 20 minutes in the second half when we rained crosses in but couldn't convert."
