Newcastle United 0-1 Arsenal

Arsenal have scored only three goals in the Premier League this season and two of them have been own goals

An own goal from defender Fabricio Coloccini gave Arsenal an unconvincing victory over 10-man Newcastle.

Arsenal scored early in the second half when winger Alex Oxlade-Chamberlain's angled shot on the rebound clipped Coloccini's heel and went into the net.

The hosts had earlier seen striker Aleksandar Mitrovic sent off in the 16th minute for a rash challenge on Gunners midfielder Francis Coquelin.

Newcastle failed to register a single shot on target in the entire contest.

Arsenal have not lost at St James' Park in the league since December 2005 and have won their last eight games against Newcastle, scoring 21 goals and conceding just six.

Newcastle boss Steve McClaren has still to to taste victory in the Premier League after four matches at his new club.

Arsenal's lack of goals still a concern

Arsenal manager Arsene Wenger described his side's start to the season as "very average" before this game and although the Gunners secured three points at St James' Park their strikers continue to misfire.

After Mitrovic's 16th-minute dismissal, Arsenal dominated possession in the final third of the pitch but were unable to turn that superiority into goals.

Theo Walcott's best effort was to lift a chance he should have scored over the crossbar while substitute Olivier Giroud made little impact when he came on.

With the transfer window set to close on Tuesday, Arsenal's supporters will be hoping Wenger has a goalscorer lined up from somewhere.

McClaren must control Mitrovic

Newcastle signed Mitrovic from Anderlecht for £13m in the summer and the Serbia international arrived with a reputation as a volatile player.

McClaren had already said that the 20-year-old must show more "emotional control" after yellow cards in his first two Premier League games.

After Mitrovic's senseless high tackle on Coquelin, the former England manager's words will need to be much tougher than that.

McClaren felt the sending off was "harsh" and "clumsy" but he cannot afford to be playing matches with 10 men and at the moment Mitrovic looks like a red card waiting to happen.

Are the Gunners title challengers?

This is supposed to be the season that Arsenal graduate from top-four regulars to title contenders.

At the moment it's hard to build a compelling case that they will rival teams like Manchester City, although it is still very early days.

Wenger was pleased with the way in which his side "kept our nerve" and described their display as "mature and intelligent".

It's an old cliche that champions have to win ugly but if Arsenal have serious ambitions on the top prize they should be breezing past a 10-man Newcastle side.

Managers' reaction

Newcastle boss Steve McClaren told BT Sport: "All we could do is show spirit and fight and they were magnificent. What a crowd as well. It was a harsh red card. It was more clumsy and he stood on his foot. I just felt early on there were too many yellows and it was a rod for the referee's back."

Arsenal manager Arsene Wenger told BT Sport: "We were always on top. We were mature and intelligent and the win was important so maybe we were a bit cautious. They toughened the game up, they decided from the start to make it very physical but we kept our nerve."

'Arsenal are going to struggle this season'

BBC Radio 5 live's Danny Mills: "On the balance of play, Arsenal have probably deserved to win. It's three points, and the style of this performance will be forgotten about if Arsenal continue to improve. But do they have the out-and-out cutting edge to challenge for the title? I think Arsenal are going to struggle this season."
