Milner has been a key player for Villa this season, scoring 10 goals in all competitions.
“James was a wide player, but he has always preferred to play in the middle. He has been doing really well,” said the Bulgarian.
“His energy is amazing and he has helped the team a lot. He can play anywhere.
“He has been brilliant – and if he continues to progress like that, he will be the star of the World Cup. He has both the ability and the attitude to make a real impact.
“He has scored 10 goals from midfield, which is really good. He has the licence to get forward and he shows great composure in front of goal.
“His work-rate is great, as well. He deserves everything he gets.”
