The Liverpool teenager has previously represented Wales’ Under 19s but received his first senior call up on Wednesday for their upcoming World Cup qualifier against Republic of Ireland.
Jurgen Klopp has been keen to protect the 17-year-old from the spotlight and only found out about Woodburn’s inclusion when the decision was made public.
And the German boss says he was expecting a call from Coleman prior to the announcement.

Chris Coleman didn't let Jurgen Klopp know he was going to select Ben Woodburn
I’m not sure if he knows him well. He didn’t play in the team so far for Coleman I think. But no call.
“Actually, I was surprised about this,” Klopp said.
“I don’t know exactly how it’s normal here. This should not be a criticism, but usually when you call up a player, a 17-year-old player, I thought it would be possible to call me.
“I’m not sure if he knows him well. He didn’t play in the team so far for Coleman I think. But no call.”
Woodburn has only made seven first-team appearances for the Reds and Klopp says he would have preferred the forward to be given more time to develop at Anfield before being elevated to the Wales national team.

Jurgen Klopp has handed Ben Woodburn seven first team appearances
“If he stopped learning now, that would make no sense at 17,” Klopp added.
“I’m not in doubt about this. We didn’t hide him. We used him all the time. He’s a fixed part of our training. He can deal with the nomination for Wales 100%.
“It’s a little bit like my situation. As long as you give me the time, as long as we give him the time, everything will be good.
“He has to learn, he has to develop, he has to improve, all of this. That’s why I said there are now two managers responsible for him. Until now, it was only my job.”
