Manchester United attacker Daniel James revealed his anger when a move from Swansea City to Leeds United fell through in "crazy" fashion last year.
James, 22, was on the verge of joining Leeds in January 2019, just months before his switch to Old Trafford.
The 10-time Wales international said he had agreed to head to Leeds before the move fell through as the window closed.
"I got to Elland Road about 6pm, did all the pictures with my shirt, all the interviews, because they wanted it to go out in the morning, and then it was strange," James told former Swansea team-mate Kenji Gorre on the Living The Dream podcast.
"It got to about 9pm and I'd signed all the papers and then it was from club-to-club. I had people texting me saying, 'What's happening?' and I literally didn't know. It wasn't until 15 minutes to go until I thought, 'This might not happen now.'
"I ended up ringing the chairman [of Swansea] to ask him what's happening. It was all a bit crazy and then it wasn't done. I threw my phone.
"I thought it's not real. The chief exec of Leeds wasn't happy at the time, but then it was just a case of driving home. It was a very weird situation and I think it helped me in some ways."
James ended up finishing the season with Swansea before joining Manchester United for a reported £15million in June 2019.
He had scored four goals in 37 games in all competitions for United before the season was suspended due to the coronavirus pandemic.
