What comes next in this international break, I hear you ask...
Scotland kick-off the Euro 2020 qualifying action at 15:00 GMT against Kazakhstan tomorrow, while Northern Ireland host Estonia later on Thursday (19:45 GMT).
England welcome the Czech Republic on Friday (19:45 GMT) and the Republic of Ireland are away to Gibraltar on Saturday (17:00 GMT).
Then, it's Wales turn on Sunday as Slovakia come to town (14:00 GMT).
Got all of that? Good.
John Tudor: Well done Woodburn, a scrappy goal, but a goal - a nice win.
So, it's a case of job done for Wales ahead of their Euro 2020 qualifying opener against Slovakia on Sunday.
A resilient Trinidad & Tobago threatened to keep a sell-out crowd quiet at the Racecourse Ground, but Wales were superior in the second-half and in the end were good value for their goal.

And here's your niche stat of the day...
Since losing 0-1 to Costa Rica in February 2012, Wales are now unbeaten in their first match of a calendar year in each of the last seven years, winning five whilst drawing the other two.
Germany rescue a draw against Serbia.
Joachim Low's new-look side were booed as they exited the pitch 1-0 down at half-time, but Leon Goretzka rescued it for his side.

We do have a late winner!

Meanwhile, Germany are still chasing a late winner against Serbia following Leon Goretzka's equaliser...

We'll have four minutes of added time! Late drama anyone?
Ben Woodburn has another half-chance for Wales, again with his head, but as has been the case on a couple of occasions this evening he can't quite direct the cross goal-bound.
Trinidad look more than happy to leave Wales with a solid clean-sheet and a disciplined display. Wales would love a last minute winner here though, if only to thank their great support.
No goals so far as we enter the final five minutes, but there have been some promising periods of play by Ryan Giggs' experimental side tonight.

This Trinidad team is starting to look a bit tired, the changes have livened it up a bit but Wales have still struggled to create clear-cut chances. There are no poor national teams anymore.
Trinidad are organised and honest - they work ever so hard and double up in wide areas so they are making things difficult - you can't play at 50%.Copyright: Getty Images
Wales' George Thomas and Trinidad's Kevan George clash in the air, with both suffering awkward-looking falls. Both are back on their feet after a short breather as we approach the final 10 minutes at the Racecourse Ground.
It's all Wales at the minute.
Lee Evans rushes in at the back-post and pokes the ball towards the bottom corner. It's well kept out once again by Trinidad goalkeeper Marvin Phillip, but the home side continue to press for a winner...
Ryan Giggs sends on Schalke 18-year-old Rabbi Matondo for the final 20 minutes.
There's plenty of excitement around the former Man City winger's potential. Can he have an impact tonight?
He replaces Tyler Roberts.

It was a lovely dink and a lovely header by George Thomas but he was offside.
