Daniel James is set to become Manchester United’s first summer signing.
The Swansea youngster has had a medical on Thursday morning and will finalise the deal today.
James will complete a £15m move to Old Trafford and become Ole Gunnar Solskjaer's first signing.
He will complete the transfer on Thursday before travelling with the Wales squad to Croatia.
In an emotional Instagram post, the 21-year-old vowed to make him proud.
The post read: "There is not one day goes by that I don't miss you, you are my inspiration and I wouldn't be where I am today without you.
"I couldn't be prouder as a son. You have never pushed me into anything I didn't want to, you always wanted me to do what makes me happy.
"Words can't describe the pain I'm feeling now. I just want you to know how much I love you and how much you will be missed by all of us.
"You put a smile on everyone's faces with your silly jokes and never failed to make anyone laugh.
"Thank you for everything you have ever done for me I couldn't ask for anyone better, I will make you proud I promise!"
