José Gomes spoke of the improvements his team need to make before the season starts in a fortnight's time, but praised the improvements the squad have already made on their two-week Spanish training camp.
The tour came to an end after the Royals were narrowly defeated by La Liga outfit, Granada, on Saturday night in Marbella - the last of six friendlies played while in southern Spain.
"It was very good training - very tough for them because of the very high temperature, and they played for 90 minutes," the Reading boss said after the match.
"Both opponents changed all their team, and our players stayed on for the whole game - we just changed Yakou for Barrow.
"All the other players played 90 minutes against a Spanish first league team, so they were good players with a good dynamic.
"Physically, it was a very tough day for them. They showed some very important things that we must improve.
"But for another side, there were a lot of positive things - a lot of good movements and things we can use in the future to help create goal situations.
"What's missing in our game is goals, so we must find a way to score otherwise we cannot win, and we want to win a lot of games during the season."
With six matches played and two full weeks of intensive training to look back upon, the manager spoke of the value of the Royals' pre-season training camp in Estepona and how he hopes for it to provide a springboard into the season.
"It was a very good training camp," he added. "Some small things - no major injuries, which is very good. After so many sessions and games, no injuries at all.
"The players worked every day, sometimes twice a day, we played two games per day so six games in two weeks was very good, very positive.
"We improved a lot, and even in these two games today, they showed us the ways that we must improve for the future.
"Next week we have more games, and in the last game of the week against Chelsea, we must be ready for the competition that we have in front of us."
