The New Saints were Welsh champions for a 17th time last season
Cymru Premier champions The New Saints could not find a breakthrough as a tight Champions League first qualifying first leg against Shkendija of North Macedonia ended goalless.
There was very little to choose between the sides, who both had chances to break the deadlock at Park Hall.
TNS record signing Ben Wilson was denied a debut goal while Shkendija's Vane Krstevski saw an effort hooked off the line by Danny Redmond.
The return leg takes place in Skopje in a week's time with a second qualifying round tie against FCSB of Romania or Andorra's Inter Club d'Escaldes awaiting the winners.
Saints last season became the first club from Wales' domestic league to reach the Europa Conference League group stages.
This was not the first time these clubs had met, having faced each other at the same stage of the competition in 2018.
On that occasion, after losing the first leg 5-0, Saints secured a 4-0 win in the home second leg but ultimately fell short as they were beaten on aggregate.
Saints boss Craig Harrison acknowledged this was an opportunity for some revenge over the North Macedonian champions.
Harrison's starting team included three new faces – goalkeeper Nathan Shepperd, defender Dominic Corness and striker Wilson.

Wilson had the game's first chance, heading over from a cross by Rory Holden, who saw a shot deflect wide of the post in what was a positive start by the hosts.
The sides were evenly matched, with Fabrice Tamba's shot from the edge of the box gathered by Shepperd before Liridon Latifi blasted over the bar.
A strong run from Corness opened up the Shkendija defence before the former Liverpool player found the advancing Jordan Williams in the area, but he fired over.
Saints had a let-off when Latifi failed to connect with a dangerous cross while Redmond made a crucial tackle to deny Fiton Ademi.
Saints lost key midfielder Leo Smith through injury and Ryan Brobbel had a shot saved by Baboucarr Gaye before the break.

Shkendija gave Saints two early scares in the second period, as Endrit Krasniqi's curling effort was turned past the post by Sheppard before Latifi flashed a header wide from the resulting corner.
It was an end-to-end opening to the half as Williams and Brobbel fired over, then Wilson found himself through on goal but his shot was smothered by Gaye, who also saved Corness' long-range effort.
Substitute Vane Krstevski then chipped over Shepperd but once again Saints captain Redmond came to his side's rescue as he cleared off the line.
The New Saints boss Craig Harrison told BBC Radio Shropshire:
"It was a pretty even game possession wise but I think we created the better opportunities. In the first half we had three or four opportunities that we should have done better with.
"In the second half we've had a big chance and it's a good save by the goalkeeper to be fair – he's a big lad and he's got his whole frame out and kept it out.
"Maybe a 1-0 win probably would have been deserved on opportunities.
"I'm happy with the clean sheet but a little bit disappointed that we couldn't score a goal."
