Liam Moore says the Royals' training camp in Spain has been a valuable learning curve for a young squad, after rounding off against Granada on Saturday evening.
A winner from Azeez late in the second half gave the La Liga side a 1-0 victory on the night, with the Reading skipper saying the match proved a valuable test.
The Royals will fly home on Sunday, before continuing their preparations in the fortnight leading up to the new season.
"It was a good test," he said after the game. "It was very similar to the Championship in terms of the physicality.
"We didn't quite get the stats we'd like in terms of numbers and distance hit, because of the temperature and the humidity.
"All in all, it was a good test. It shows that we've still got a lot to work on, we've got a really young squad and we're going to have to pull together over the next couple of weeks and be ready for when the first game comes.
"It's been a tough training camp. We've had a lot of training sessions, a lot of games. Ideally, as the manager said, we'd have liked to brought together more of a team - like a few people over here that he'd have liked.
"It didn't happen like that, but we've cracked on. The young lads have been a credit to the club, they've really dug in.
"Some days, they've actually had to play two games in a day - which is a big ask. All in all, I think everyone will be going home happy."
The Royals had two new arrivals while over in Estepona - goalkeeper, João Virgínia joined the squad over in Spain, while new defender, Michael Morrison will join in training from Monday - and Moore and Morrison's paths have crossed before.
"I was just trying to break through at Leicester when he was there," he continued. "I know of him, I watched a lot of football back then at Leicester.
"He's very solid, he'll bring a lot of leadership to the team - which is good for the youth, and he's a winner, which is a really big thing.
"It's important that you have players in your team that'll win at all costs, and I'm pretty sure he'll do that."
