Former Newcastle United striker Patrick Kluivert is backing his old club's pursuit of FC Twente striker Luuk de Jong.
De Jong has been watched personally by Toon boss Alan Pardew in recent weeks.
Kluivert, McClaren's No.2 at FC Twente, said: "Luuk [de Jong] is going to be the No.1 striker for Holland in the very near future.
"He has everything a striker needs.
"Here at FC Twente we are grooming him for a future with one of Europe's biggest clubs.
"He can become a European giant.''
