Wales came out on top in Sunday's crucial World Cup qualifying match, with Gareth Bale again the man for the big moment.
His first-half free-kick was deflected in by West Ham's Andriy Yarmolenko, and was the only goal of the game as the hosts sealed a 1-0 win.
Ukraine piled the pressure onto Rob Page's side, but a standout performance from goalkeeper Wayne Hennessey ensured Wales held on for the win.
The constant downpour of rain only added to the tension at the Cardiff City Stadium, with Wales putting on a stubborn defensive display to end Ukraine's World Cup dreams, just days after they beat Scotland at Hampden Park.
As a result, Wales have now qualified for the 2022 World Cup in Qatar, where they'll join Group B alongside England, Iran and the United States.
They'll play their first World Cup fixture for 64 years on November 21 - the opening day of the tournament. Their first game comes against the United States.
Ben Davies was at the centre of Wales' desperate defence, and the 29-year-old described qualification as a "dream come true".
"There was a lot of emotion in this game, but we stood up brilliantly," said the Tottenham Hotspur defender.
"Every challenge they threw at us we dealt with.
"It's incredible, a dream come true, as a squad we've worked so hard for this.
"We may not have the most talented group but we give it everything we have got."
Rob Page praises Welsh support
Following the win, Rob Page immediately praised the Welsh support in the Cardiff City Stadium.
"I'm so proud of the guys, they thoroughly deserved it," said the 47-year-old manager.
"The one thing these boys were missing was a World Cup and now we've got there.
"These are the best supporters in world football, they helped us from the first minute.
"When you see what these guys do in training, I had full trust in them."
