Wales kick-start their Euro 2020 qualifying against Slovakia at Cardiff City Stadium this afternoon.
Ryan Giggs' side warmed up for the game in the Welsh capital with a narrow 1-0 friendly win over Trinidad and Tobago at Wrexham's Racecourse ground, with Slovakia beating Hungary in their first qualifier 24 hours later.
And the hosts will have to cope without Aaron Ramsey for the visit of Pavel Hapal's side, with the Arsenal man failing to recover from a thigh problem.
There's set to be a packed crowd at Cardiff City Stadium as Wales look to begin their qualifying campaign with victory over the side they defeated in their first match of what was a memorable Euro 2016 campaign.
And you can follow live updates from today's huge encounter right here.
Kick-off: 2pm
WALES v SLOVAKIA
Good morning everyone!
It’s a glorious sunny day here in Cardiff.
And the time for talking is almost over.
It’s the Euro 2020 qualifiers. It’s Wales v Slovakia.
Big match for Wales this Sunday as we begin our Euro 2020 qualifying campaign.
The match at Cardiff City Stadium kicks off at 2pm. It is live on Sky Sports and S4C.
Slovakia beat Hungary 2-0 at home in their opening qualifier, while we warmed up for this with a highly weakened team beating Trinidad & Tobago 1-0 at Wrexham.
Wales midfielder Aaron Ramsey will miss the opening Euro 2020 qualifier against Slovakia on Sunday after failing to recover from injury.
The 28-year-old Arsenal player has been withdrawn from the squad and returned to his club for treatment.
Ramsey did not feature in his country's 1-0 friendly win over Trinidad and Tobago on Wednesday.
"We have plan B and we've worked on it during the week," said Wales manager Ryan Giggs.
"He was in good form but it gives a chance for someone else."
Wales have been boosted by the news that Bournemouth midfielder David Brooks has been passed fit after the 21-year-old missed Wednesday's game with an ankle knock.
Ramsey's absence could also open up an opportunity for Matt Smith, Lee Evans or Will Vaulks to play a key role in Sunday's match.
Defender Ethan Ampadu and forwards Sam Vokes and Tom Lawrence also missed Wednesday's friendly and are unlikely to feature against Slovakia.
