Santi Cazorla scored a 94th-minute penalty as sub-par Arsenal beat Southampton on Saturday with Laurent Koscielny’s overhead kick having earlier cancelled out Petr Cech’s own goal.
Cazorla held his nerve after Jose Fonte was penalised for tangling with Olivier Giroud in the box as Arsenal took all three points in a match they had appeared destined to draw.
Southampton took the lead in the 18th minute when Cech touched Dusan Tadic’s shot onto the crossbar, only for the ball to ricochet down and bounce over the line off the goalkeeper’s head.
Arsenal, who handed debuts to new signings Shkodran Mustafi and Lucas Perez, heaped on the pressure and were rewarded in the 29th minute when Koscielny slammed home a fine overhead kick as Southampton failed to clear their lines from a corner.
Watford came from two goals down to beat West Ham 4-2 in the English Premier League on Saturday for its first win of the season under new manager Walter Mazzarri.
Michail Antonio scored in the fifth and 33rd minutes for West Ham to move up to four goals for the season — all of them headers — before his team imploded in its second league match at the Olympic Stadium.
Watford scored four goals in a 22-minute spell around halftime, starting with Odion Ighalo’s deflected shot in the 41st minute.
Troy Deeney pounced on a defensive mistake to make it 2-2 in first-half injury time, Etienne Capoue scored his third goal of the season, and Jose Holebas finished off the comeback with a low shot that West Ham goalkeeper Adrian should have saved.
South Korea forward Son Heung-min scored twice and Harry Kane netted his first goal of the season Saturday as Tottenham thrashed Stoke 4-0 away in the English Premier League for the second straight year.
Dele Alli also scored for Tottenham in its best performance so far this season, which kept the team unbeaten after four games.
The first of four goals in a damaging 29-minute period for Stoke came in the 41st when Son volleyed in Christian Eriksen’s cross to finish off a sweeping counter-attack.
The same two players combined for Son’s second goal in the 56th, before Alli made it 3-0 in the 59th by slotting home from Kyle Walker’s cross.
Kane completed a one-sided win with his 50th Premier League goal, tapping in Son’s low cross to end his 10-game drought for club and England. Kane was the top scorer in the league last season with 25 goals, having only scored his first goal in October.
He has also started this season slowly, even playing out of position at times to accommodate new signing Vincent Janssen.
Tottenham, which was the most persistent challenger to champion Leicester last season before eventually finishing in third place, has eight points with two wins and two draws.
Stoke is bottom of the fledgling standings on one point from four games, and has conceded four goals in both of its home games so far.
