Admittedly I don't hold onto matches and events like some seem to but you'll have to jog my memory about instances when we've been playing our direct rival's title rival, in the penultimate game of the season, where a victory over that team will essentially hand Arsenal the title. I can't remember that scenario, could you remind me of which season that was?
You're right, we do play them twice a season. This season, we've given them 6 points. We've given City 4 points.
You're right as well, the mentality should be that Tottenham need to win a football game and I expect that was exactly what Ange's and the players' mentalities were. Despite hyperbole about what John from Brentwood is nattering on about in the crowd or a 'winning mentality' from the club that's the actual fundamental point about how the players and manager do.
