Alexis Sanchez slotted a penalty into the net deep into stoppage time to give 10-man Arsenal a 2-1 victory over Burnley on Sunday, sending the north London club up to second in the Premier League.

Burnley looked like taking its second point on the road this season when substitute Francis Coquelin tripped Ashley Barnes and Andre Gray powered home the first spot-kick in stoppage time to cancel out Shkodran Mustafi's header.

But, in the last of the seven additional minutes, referee Jon Moss, who had already dismissed Granit Xhaka and sent Arsene Wenger to the stands, pointed to the spot once more and Sanchez secured the three points.

Southampton condemned Leicester to the 11th loss of its Premier League title defense with a 3-0 victory on Sunday, leaving the champions five points above the relegation zone.

James Ward-Prowse, Jay Rodriguez and Dusan Tadic scored as Southampton eased to victory, leaving Claudio Ranieri's Leicester looking short of ideas in attack and worryingly frail at the back.

Southampton's joy was tempered by an ankle injury to captain Virgil van Dijk, leaving Claude Puel's team short of center backs after Jose Fonte's move to West Ham.

Leicester's decline continued unchecked on the south coast as last year's defensive linchpins Robert Huth and Wes Morgan were exposed.

Huth inadvertently laid on Southampton's second goal, his attempt at a headed clearance turning into a knock-down that let the lurking Rodriguez sneak in and finish with relish in the 39th minute.

And a potential own goal from Morgan was ruled out due to a foul from Maya Yoshida. That reprieve hardly spared the visitors' blushes however, with Tadic scoring a penalty in the 86th after Morgan fouled Shane Long.
