Arsenal fans celebrated St Totteringham's Day on Sunday. Again. For the past 21 English football seasons, Arsenal followers have indulged in their favourite bit of Schadenfreude: finishing above Tottenham in the league. No matter what your allegiances (aside from those mean-spirited Gunners supporters, that is) you have to feel for Spurs. Going into the final day of the league they sat above Arsenal, Chelsea, Manchester United and Liverpool.They regularly had more players in England squads and on Monday they had the most again - five, along with Liverpool. And they have another three in the Belgian squad for the European championship.All they needed was a draw against one of the worst teams in the league, Newcastle. If you had been with Matt Damon on Mars you would have thought the league title was a done deal. Except, of course, there had been the matter of Leicester City running rampant throughout the season, and Newcastle running rampant on Sunday, sending Tottenham fans (all good people, to my knowledge) into mourning with a 5-1 demolition.Arsenal pipped Spurs late on Sunday afternoon and the St Totteringham's Day celebrations began, with even Lukas Podolski, the former Gunners striker, and their goalkeeper Wojciech Szczesny, who is on loan to Roma, gloating. Sies!It made you want to buy a Spurs fan a drink, or knock Olivier Giroud off his bicycle.There are many theories about where Tottenham went wrong. First, what went right. They exceeded expectations, having failed to qualify for the Champions League last season by a long way. Mauricio Pochettino has helped them develop a hard-pressing, attacking style that brought them success - until Sunday.Part of the problem might have been that the Argentinian manager relied too much on Heung-Min Son, Tottenham's most expensive signing last year at £22-million, linking with Harry Kane up front in his 4-4-2 formation. For much of the season the South Korean was injured, however. With Plan A crocked, Spurs drew too many games they should have won.Those who know about such things suggest Tottenham's is a possession-based game similar to that of Pep Guardiola, who will be in charge at Manchester City next season, and of Thomas Tuchel, the Borussia Dortmund coach, with a bit of influence from Marcelo Bielsa, under whom Pochettino played at Newell's Old Boys and with Argentina.I say: bollocks! It's all about the curse of St Totteringham's Day. It's a holy day for Arsenal fans, who celebrate when it becomes clear that Tottenham cannot finish above the red half of north London in the league.It's the day when Gunners fans collect on bets made by ever-optimistic Spurs fans in the off season who think that "this is our year".This year it happened on the last day, but it has - on rare occasions - come as early as March. According to an anally retentive Arsenal statistician (there's a tautology!), the Gunners have been above Spurs in the league in 65 seasons. Spurs have surpassed Arsenal 30 times. When Spurs and Arsenal have been in the same division (and that's always been in the First Division or Premier League) Arsenal lead 50-28.The curse goes back to 1911, when Tottenham were first in the same league as Arsenal, but the most recent evidence (aside from the Rafael Benitez-inspired rout on Sunday) goes back to 2012, when Tottenham qualified for the Champions League by finishing fourth (another St Totteringham's Day year). But because of a bizarre ruling by the Uefa, Chelsea, who finished sixth, were allowed to defend their 2011 European title - at Spurs' expense. They changed it the next year.Somebody has it in for Spurs and I suspect it's St Totteringham...
