Celtic boss Ange Postecoglou has no doubts about Matt O'Riley's commitment.

The Dane is being linked with Newcastle United.

But Postecoglou said: “Perspective is always a good thing.

“You could say Matt has had a meteoric rise, but this time last year he was playing with MK Dons in League One, so I think he understands the other side of football.

“He was literally training in the park with his dad and a personal trainer not all that long ago, so he's seen that side of it.

“When things are going well you understand that the only reason things are going well is because you are doing certain things, you're staying in the present, you're working hard and making sure you are the best footballer you can be.

“You can't worry too much about speculation or what the next step is — the time when footballers maybe fall into the trap is when everything's gone well for them and there are no setbacks.

“Even the best players in the world have setbacks, and Matty has had that.

“It's been fantastic for his development as a person as well as a footballer to understand that, as well as things are going now, they'll only keep going well if he keeps doing what he's doing."
