Kovac urged supporters and media alike not to rush their judgement on the teenager, stressing that his role is still being defined.
"We let him play there at the Club World Cup because we wanted to see how he would adapt. But I do think the number six role is where we see him long-term. I don't want to make comparisons, but he has a lot of potential. But that has to develop first; it's a process. You can't make the mistake of putting too much pressure on him because of his name. That's not doing the boy any favors."
He added: "Jobe is a very talented young player who comes from the English second division and has to grow into his new role here. We know exactly what we expect from him and what the future holds. The jump from the English second division to the Bundesliga – that's a natural fit. He's getting good minutes and has played in every game. Everyone wants to play more. I'm happy with his development. When you sign a contract here, you know there's a lot of competition."
