#3 Celtic (Scotland) - 51 titles
Scottish powerhouse Celtic, who lifted their 50th league title in 2018-19, were awarded their 51st league title last campaign after the Scottish season was abandoned due to the COVID-19 pandemic.
After Rangers won the first two Scottish league titles of the 2010s, Celtic have now won all of the next nine on offer.
In fact, Celtic, along with Italian giants Juventus and Bulgaria's Ludogorets Razgrad, have the longest active run of consecutive league triumphs in Europe, with the trio having won their last nine league titles.
#T1 Linfield (Northern Ireland) - 54 titles
Northern Irish champions Linfield, who won their 53rd league title in 2018-19, were awarded their 54th last season after the COVID-19 pandemic forced a suspension of the season.
With their latest triumph, their third in the last four seasons, Linfield are 31 clear of closest challengers Glentoran as they won a record-equalling 54th league title, the joint-most by any club team in Europe.
#T1 Rangers (Scotland) - 54 titles
The 'other' giants of Scottish football, Rangers, won their 54th league title almost a decade ago when they beat their arch-rivals Celtic by a point in a thrilling title race in 2010-11.
Since then, Rangers have fallen on hard times. A financial crisis in 2011-12 saw the club go into administration and subsequently demoted to the fourth tier of Scottish football.
Rangers won three promotions in four years to return to the top flight in 2016-17. In their four subsequent seasons in the first division, the 54-time champions finished behind Celtic twice, which includes the unfinished 2019-20 season that was suspended because of the COVID-19 pandemic.
With Liverpool legend Steven Gerrard at their helm and a decent group of players at their disposal, the fallen giants of Scottish football will look to end Celtic's nine-year stranglehold of the Scottish league title and return to winning ways for the first time in a decade.
