Giggs took charge of four Red Devils games as caretaker manager following the sacking of David Moyes in 2014.
Louis van Gaal was chosen as Moyes’ permanent successor with Jose Mourinho taking the reins after the Dutchman was shown the door.
Ole Gunnar Solskjaer is now in charge of the Premier League giants with his former team-mate Giggs at the helm as Wales manager.
Giggs has opened up on not getting the United job following Moyes’ departure and acknowledges that he probably won’t get another chance.
Giggs told The Greatest Game: “If I’m honest, I wanted the job [after Moyes was sacked]. But I wasn’t ready.
“I’m more ready [for the United job] now but I think that’s gone now, I think the chance has gone now. I think it’s gone, I’ve done it.
“I’m happy with the job I’ve got. I can’t see that coming around again.
“I must say I’m enjoying the [Wales] job at the moment. There’s lots of pluses, and there’s lots of frustrations.
“I think eventually I will want to go into club management, but when that is, I don’t know.”
Giggs also opened up on his first meeting with Van Gaal, claiming the Dutch legend punched him.
Giggs added: “He was different. He was very dominating. The first time I met him he punched me in the stomach.
"I’ve gone to meet him, we’ve got a list of players that I think were good and the ones that were not so good.

“I’ve gone to meet him a hotel, he’s opened the door, looked me up and down and gone ‘you are in good shape!’ then he punched me in the stomach.
