Speaking to The Daily Express, Wenger said, "What these players have already achieved, at that age, is remarkable. These players are winners, they will deliver, and they are very, very young.
"To be in the last four in Europe, and to come back above Aston Villa after being eight points down is remarkable. I believe the future looks very bright.
"We had William Gallas, Gael Clichy, Emmanuel Adebayor, Theo Walcott and Cesc Fabregas out for a long time. And Tomas Rosicky did not play one game in the season. Can you believe that? And that’s why I believe what we have achieved, despite all that, is remarkable."
The Frenchman sees the Champions League penalty shootout win against Roma as a vital part of his team's development.
"On that day against Roma, I felt this team has not only quality but mental strength," he said.
"And the (4-4 draw) Liverpool game for Arshavin was something special that happens to you once in a career – but only if you are a special player.
"The match itself was something amazing. It was, maybe quality-wise, the best game of the season.
"I admire his talent, his personality, his winning attitude and his efficiency and I’m convinced he will be a big hit.
"We’ll also have Rosicky and all the young players who have learnt a lot this year, so let’s be positive, optimistic and brave."
