Gavin Strachan's key role in Reo Hatate's Celtic form revealed

The Japan international was recently left out of the country's squad for the World Cup and the 57-year-old detailed that, while the Hoops playmaker was disappointed, he has used it as motivation to improve.

Part of this development was working closely with Strachan on improving his numbers in the final third.

Postecoglou said: "All the coaches have individual responsibilities and he [Hatate] falls under Gavin Strachan's portfolio. Gavin will be the first to tell you that Reo is always the first in the door after a game asking for feedback.

"He is just that kind of player as he is constantly asking how he can improve and what areas he can get better in. I haven't had too many conversations with him. Usually, when he comes to see me he just wants a clear direction.

"Last year I felt that his fitness levels weren't where they should be and I felt he was dying in the last part of the games and he worked really hard on that. I think he is a lot better this year and a lot stronger.

"He asked me what the next layer was. I said to him for him to be the player he wants to be, and I know he has got it in him as he has always played in an attacking way, he has to have greater attacking output."

The Australian also provided a transfer update on Giorgos Giakoumakis. 

It has been reported the Greek striker has agreed a deal with MLS side Atlanta United, however the move is yet to be confirmed.

It appears the former Yokohama F Marinos coach wants the situation sorted sooner rather than later as he claimed it is "no longer on his radar".

It will get concluded fairly soon,” he continued. “To be honest, it’s not on my radar any more. I will probably hear it about the same time as you guys. Maybe if you are on Instagram you will hear about it earlier than me.

“It’s not on my radar, I don’t expect him back in the group, but it hasn’t been finalised yet."
