'Marco van Ginkel is one of the best prospects. He is not yet like Schurrle - close to being a finished product - but he is a player with great potential.
'Of course he needs to play and he will, because he is a player with great potential and physically he is more than ready. He is a natural athlete. By the technical and the tactical point of view of course he is a kid, he has to learn, but I think he is very open-minded and we analysed him for quite a long time. The Chelsea scouting department did it for quite a long time and I did it in the last five or six months, and we made a collective decision to bring the kid here.
Mourinho confirms that three additions to the squad for next season are Romelu Lukaku, Kevin De Bruyne and Tomas Kalas, after their successful respective loans at West Brom, Werder Bremen and Vitesse.
'They are good players with a very good value in the market and we have these players this season for free, after an investment that the club did before,' he says.
'After the development of the players on loan it is the right moment for them to be back. They are very young with space to develop, they will be better year after year and I can imagine in five years they are much better than today - but what they have today is more than enough to belong to this squad.
