Oh Hyeon-Gyu's determination to join Celtic was crucial in getting the deal done, according to Ange Postecoglou.

South Korea international Oh became the champions' fourth signing of the January transfer window on Wednesday morning.

The 21-year-old has joined on a five-year contract, subject to international clearance, and for a reported fee of around £2.5million.

Postecoglou insists it was more than just Oh's footballing talent that led to the acquisition, with the player's persistent and ambitious personality key to ensuring the deal got over the line.

Postecoglou said: “We are delighted to bring Oh to Celtic. He is a young, talented striker with great attributes and someone who is ready to take the next stage in his career – a player who is hungry, eager to develop and to achieve success.

“I have watched Oh for some time and he is the striker I really wanted as I think he will be a great fit in our squad.

“Really importantly, I know that he had his heart set on joining us too and that his own perseverance has been crucial in making this deal happen, so his determination to join Celtic has been very clear.

“We are really pleased to welcome him to the club and look forward to working with him and settling him into our squad.”
