There has been a whole list of bright prospects over the summer and with the World Cup, fans, teams and managers have had the opportunity to see these young stars in action.
Some of these moves have linked to transfers already. Chelsea get the return of Thibaut Courtois; the Belgium international spent a few seasons out on loan, and last year he was a major part into why Atletico Madrid were so successful both in Spain and in the Champions League.
Another Belgium player with huge potential is Divock Origi. The winger plays for Lille in Ligue 1 but reports suggests that he is being targeted by Liverpool and to be loaned out back to Lille straight away.
Manchester United new boss Van Gaal set his sights on Southampton left-back Luke Shaw. Shaw made appearances in the World Cup for England and now he will play at Old Trafford week in week out.
Adam Lallana and Rikie Lambert also represented England this summer and they too saw moves away from Southampton; Liverpool were their destination and they join English teammates Daniel Sturridge, Jordan Henderson, Raheem Sterling and Steven Gerrard.
Southampton also sold Dejan Lovren and Calum Chambers, while Morgan Schneiderlin could be on his way out too with Tottenham eyeing up the French midfielder.
This leaves Southampton with a substantial amount of transfer budget. They have added Graziano Pelle and Dusan Tadic to their squad already but will need more if they want to progress within the Premier League and push for a Europa League spot.
The Saints may be looking to bring in another attacking midfielder with a bit of flair who could replace Lallana's quality.
Arsenal too have had their eyes set on one of these young prospects and manager Arsene Wenger was particularly interested in the Dutch dead-eye Memphis Depay.
The midfielder currently plays in the Eredivisie for PSV but with the range of quality already at Arsenal, it will be hard for Depay to break into the first-team. This then means that if a deal was to take place, the winger could be loaned out and giving him Premier League experience will be helpful for him to learn the English game.
Southampton have also shown interest in Depay but Arsenal are likely to be the player's favoured destination. However this doesn't rule out a move to Southampton. We may be in for a double move; Arsenal signing Depay and then sending him to Southampton on loan.
Next year he has more chance of featuring in the Arsenal team and this experience will unleash his potential so the move looks likely.
