But whatever happens in that game, Wales will still have a shot at automatic qualification in the final round of fixtures.

"The result was what counted, getting that was the priority," Giggs said.

"Some of the quality of the play was outstanding, we've improved since the Azerbaijan game (2-1 home win in September).

"We've started to gain some momentum, which is not easy in international football.

"Azerbaijan is not an easy place to come and there was so much on the game that it's up there with one of my best performances."

Giggs also had the benefit of giving game-time to star players Gareth Bale and Aaron Ramsey after their recent injury problems.

Bale had not played for over a month after suffering a thigh injury, but the Real Madrid forward got nearly an hour under his belt.

Juventus playmaker Ramsey replaced Bale to make his first Wales appearance in nearly a year.

"We've still got to assess it before Tuesday," Giggs said.

"Getting Gareth off pretty early and getting Aaron some minutes as well was important, When Aaron came on he showed his quality.

"It's a quick turnaround and Gareth was blowing a little bit, which you can expect.

"But hopefully I'll have the option to start both on Tuesday.

"We had to do our job, we've done it and tried put a little bit of pressure on Slovakia."

On Wales' upturn in form, Giggs added: "I would say we've had four good performances in a row, with the Belarus friendly.

"Slovakia and Croatia are top opposition and we played well. It's what we needed after the two difficult games in the summer.

"We needed to be strong and we have been. We really dug in deep against Croatia.

"I was not happy with the amount of corners we kept giving away here, but in open play they never really troubled us and we could have scored a few more goals as well."

Azerbaijan have yet to win in Euro 2020 qualifying and have picked up only one point from seven matches.

Manager Nikola Jurcevic said: "Wales deserved to win this game because they were the better team.

"We conceded goals from set-pieces, not for the first time against very big players.

"We had lots of set-pieces ourselves but the big difference between us and Wales was that they were really dangerous from theirs."
