Pundit Martin Keown has told the Daily Mail that Tottenham's success this season has caused a level of anxiety at North London rivals Arsenal.
Spurs meet Arsenal at White Hart Lane on Saturday afternoon, in a match which could be seen as win-or-bust for both title-challenging teams.
Tottenham, who lost 1-0 away at West Ham on Wednesday night, missing the chance to go top of the Premier League table, but they still sit just three points behind league leaders Leicester City.
Meanwhile, Arsenal have endured a torrid week, losing 3-2 away at an injury-ravaged Manchester United before an embarrassing 2-1 home defeat to relegation threatened Swansea City.
Arsenal's title challenge may hinge on Saturday's result, and some fans have even suggested that even if they can't win the Premier League, they simply want to stop rivals Tottenham from ending the season as Premier League champions.
Whilst there is a real buzz around Tottenham even after their midweek defeat, the feeling at Arsenal is one of discontent, with manager Arsene Wenger coming in for stern criticism.
Now, former Arsenal defender Martin Keown has told the Daily Mail that he thinks Tottenham's exploits this season are causing anxiety at the Emirates Stadium, given that Arsenal have been trying to win the league for so long, and Spurs could swoop in to win it this season.
"In 2006 it was close when Spurs almost snatched away that Champions League spot and that would have been disastrous for Arsenal," said Keown. "And in recent years Spurs have come close but never quite made it over the line,2 he added.
"Now, in the blink of an eye, it’s all changed. We have a new frontrunner in Tottenham and because of that, it’s doubly hard for Arsenal fans to get their head around. They have not been capable of winning the league for more than a decade but the last team they expected to get there before them was Tottenham. That’s why there is such anxiety at the club this season. They know there is a golden opportunity," he added.
