Royals' manager Jaap Stam says he is happy with the work that has been put in by his players while on tour in Holland.
The team have taken in 10 days of intense training sessions while out in Oosterbeek, as well as four friendlies against a mixture of high-level opposition from around Europe.
Royals played their final two matches in Holland this morning, drawing 0-0 against Sparta Rotterdam before a different selection players drew 1-1 against Belgian side Cercle Brugge.
Speaking following Saturday's matches, Stam reflected: "It is productive because we're very happy with the work the players have put in. I know it's not easy, when I was playing being away from home for 10 or 11 days isn't always an easy thing to do.
"I think it's good to get everybody together again. We talked about what we want to achieve again next season and how we do it as well, in the way of playing.
"I'm quite happy with the performance of the team and how they've been training, how they've been acting all together, and the games that they've played.
"After we come back tonight they've got two days off, then we will prepare for next Saturday against Vitesse Arnhem when they come to the UK, then the week after that we have the start of the league so we're looking forward to that.
"For now, it's very important to be working on our shape with what we want to do physically, becoming stronger and stronger.
Royals now return to England to continue their pre-season preparations, before our curtain-raiser against Queens Park Rangers in two weeks' time.
