"You can sign young players, good players with talent, but it takes time for them to realise their potential. Wenger has been using these young players for two or three years and now we are seeing them play really well with quality.
"We must wait to see whether they can maintain this through the season, but they do have enough quality to play well for a long time.
"It is what we are trying to do here. We have brought in a lot of young players, 17, 18, 19 years old. We have to wait a while for them to be ready for the first team.
"You can see the reserves now winning games with these players, some of them are really close to first-team level.
"In a few months, a few years, there will be a lot of players coming through from the reserves."
