Braintree Town manager Danny Cowley says his side will learn plenty from their FA Cup first-round 1-1 draw against League Two side Oxford United.
The National League side came from behind to earn a replay at the U's.
"I thought the boys were tested to their absolute maximum by a marvellous team, certainly the best I've played or managed against," said Cowley.
"They just ask you so many questions from restarts - they're always probing and tested us right to our mettle."
The former Concord Rangers boss continued to BBC Essex: "We won't be tested like that in the league all season. You learn a lot about yourselves, physically, mentally, technically, tactically. Watching that game I've learned loads as a coach."
Braintree went behind to Ryan Taylor's 15th-minute effort, but Kenny Davis' fourth goal of the season drew his side level in the second half, and Cowley was proud of his side's fightback.
"We lost a bit of a bit of belief when they scored," said Cowley. "The club in the last two years playing Chesterfield and Tranmere we were well beaten and I don't know if that had an effect.
"We managed to get a foothold halfway through the second half. You watch the FA Cup on Friday and Saturday and you're waiting for it to come.
"I said to them before we wanted to learn from the teams that had done well and the teams that had done well made it an FA Cup tie. It's a brilliant competition."
