Aberdeen manager Craig Brown admits he is delighted with the production line of exciting talent at Pittodrie.
Brown has paid tribute to the work being done by youth development chief Neil Simpson and coach Neil Cooper.
Youngsters such as 20-year-old defender Joe Shaughnessy are becoming regulars in Brown's team along with teenagers Clark Robertson, Cammy Smith and Ryan Fraser.
The Dons boss said: "We had four youngsters playing against Dundee United last weekend - Joe Shaughnessy, Clark Robertson, Cammy Smith and Ryan Fraser - in what was a demanding fixture.
"It is good for the club and good for the lads themselves. In our previous game against St Johnstone, 10 of the 18 players on duty for us were under 21 - and that was quite exceptional.
"The young players who are coming through have been brought on by the two Neils. They are very important guys at Pittodrie.
"When you're looking for a player to come in, you look over your shoulder and they'll say: 'Here's one.'
"Joe Shaughnessy is an example of that and was outstanding while on his year-long loan at Forfar."
