Arsenal and Tottenham grabbed late winning goals against title rivals on Sunday to move two points off the lead as the race to win the English Premier League tightened up.
Leicester started the weekend with an unlikely five-point lead but conceded in the fifth minute of stoppage time to lose 2-1 at Arsenal, with Danny Welbeck scoring the winner in his first match back after 10 months out injured.
"This strengthens our belief that we are in the fight," Arsenal manager Arsene Wenger said. "It would have been massive for us to lose."
It was only Leicester's third loss of the season — and two of them have been inflicted by Arsenal.
