And the 1972 European Cup Winners’ Cup hero believes 18-year-old Lewis Macleod reminds him of a young Barry Ferguson when he burst into the Gers first team in the late 90s.
Johnstone, speaking at the third round draw for the Scottish Cup at Hamilton Racecourse, realises that club’s rising stars will take a bit of time to get used to playing at senior level and to produce the consistent performances expected when you play for Rangers.
But so far DJ has been thrilled with the impact they have made and he hopes more kids from the Murray Park production line can make the breakthrough.
He said: “I’m just delighted that the young players that have come in have been absolutely wonderful.
“I don’t think Lewis Macleod has missed a game this season and I think he looks the part in midfield.
“He looks like a young Barry Ferguson.
“He’s somebody who always wants the ball and no matter where he is on the park he wants to get it, pass it and move.
“Kyle Hutton has also come in from the cold, he went on against Motherwell and showed his strength as well.
“The one thing we have lacked for many years is a winger, someone like Willie Johnston, with a bit of pace and young Fraser Aird has that.
“It’s wonderful to see him take people on inside and outside and having shots.
“Kal Naismith also came in at the weekend and scored so it’s great for fans to see these boys.
“But what they now need to do is get that away form going because that’s very important as well.”
