They're unbeaten in 29 games, winning 27 of them. They hold a 25-point lead. They're about to clinch a sixth straight league title this weekend and it's still not even April.

Celtic's players have taken their supremacy of Scottish soccer to a new level this season, putting the storied club from Glasgow in the conversation when discussing the most dominant sides in Europe's domestic leagues in the 21st century.

Celtic will be the Scottish champion again as early as Friday if its closest rival, Aberdeen, loses to Dundee. If Aberdeen wins, Celtic will take an unassailable lead in the Scottish Premiership by beating Hearts on Sunday.

There's been a sense of inevitability about the whole thing since the turn of the year, by which time Celtic had jumped into a 19-point lead. It's long stopped being called a "title race" in Scotland, more a procession.

Meanwhile, the team coached by former Liverpool manager Brendan Rodgers won the Scottish League Cup in late November and is also through to the semifinals of the Scottish Cup.

With Celtic's unbeaten run across three domestic competitions currently at 36 games, this might be the most dominant season by any club in the history of Scotland's top flight.

A glance around Europe shows a few other examples of title monopolies.

Dinamo Zagreb (Croatia) and BATE Borisov (Belarus) are currently on a streak of 11 domestic leagues titles in a row since 2006. Olympiakos is on course for a seventh straight Greek league title, which would be its 12th in the last 13 years, and Sheriff Tiraspol has won the Moldovan league every year except one since 2000. Basel leads the Swiss league by 17 points and is about to seal a ninth title in 10 years.

In these lesser-profile leagues, teams can dominate because of the cash they receive from participating in UEFA competitions, which often allow them to outspend their domestic rivals.

Last week, UEFA President Aleksander Ceferin, attending a conference in Lisbon, spoke of the threats to European soccer in the coming years, including the "decrease in competitive balance within European club competitions and secondary effects affecting domestic competitions."

There are examples of lopsided championships in Europe's big leagues, too: Juventus is closing on an unprecedented sixth straight Serie A title in Italy and on course for a third straight Serie A-Coppa Italia double; Bayern Munich is on course for a fifth straight Bundesliga title in Germany, which included winning one championship after 27 matches of a 34-round league; Lyon won the French league title seven times in succession from 2002; and Ajax won four straight titles in the Netherlands from 2011-14.

Scotland is widely regarded as a backwater in European soccer these days, mainly because of the uncompetitive nature of its league and an increasing lack of exposure and coverage outside Britain.

What didn't help was Rangers — Celtic's fierce crosstown rival and winner of a record 54 league titles — getting demoted to the fourth tier of the Scottish game in 2012 because of financial irregularities.

This is Rangers' first season back in the Premiership, but it hasn't been able to challenge Celtic and currently sits 33 points behind in third place. There used to be constant talk of the two "Old Firm" clubs crossing the border to join the English league but that has cooled.

"I want to win (the league) by 50 points," Rodgers, who is in his first season at Celtic, said last month.

In any other league, that would be a preposterous comment, but perhaps no longer in Scotland.

The season started so embarrassingly for Celtic and Rodgers, a 1-0 loss to Gibraltarian part-timer Lincoln Red Imps in a Champions League qualifier in July described by some pundits as the club's worst defeat in its 130-year history.

Now, they are about to lift the league title with eight matches to spare and potentially in the month of March for the second time in four years.

"We want to continue winning, continue the run that we're on," Celtic goalkeeper Craig Gordon said, "and make sure we do that for as long as we can."
