Arsenal v Tottenham: Key stats and talking points

Arsenal begin a testing run of fixtures by hosting arch rivals Tottenham, who are unbeaten away from home in the league. BBC Sport examines some of the key themes before Sunday's 198th north London derby.

The Gunners' 10-match winning streak ended with a 2-2 draw at Sunderland but they are still in a commanding position – top of the Premier League and boasting a perfect record in the Champions League.

But this is the start of a tough week for Mikel Arteta's side, with the derby followed by Wednesday's home game against Bayern Munich – arguably Europe's most in-form team – before another match versus London opposition, away to Chelsea.

They will have to negotiate this period without key centre-back Gabriel, who is likely to be out for at least a month after being injured playing for Brazil against Senegal at Emirates Stadium last weekend.

Arsenal have previously suffered when the first-choice partnership of Gabriel and William Saliba has been disrupted, but they invested in quality cover this summer. Cristhian Mosquera, Spain Under-21s captain, arrived from Valencia, while Ecuador international Piero Hincapie joined on loan from Bayer Leverkusen.

Even so, Gabriel's absence is significant. Arsenal have won 64% of the Premier League games he has played in since arriving five years ago, compared to 40% without him.

He is also a potent set-piece threat, scoring 11 goals in the past two years – including the only goal in last season's win at Spurs.

Frank's first north London derby

The injury-time equaliser Tottenham conceded in the 2-2 draw with Manchester United means they remain winless at home in the league since the opening weekend.

Away from north London, it is a different story. Spurs are the only Premier League side yet to lose on the road this season.

Nonetheless, new head coach Thomas Frank has struggled to win over supporters with his style of play. His team have yet to click in attack, averaging fewer than 10 shots per match, the third-lowest figure in the top flight.

Tottenham were booed off in their last London derby under Frank, a 1-0 defeat by Chelsea earlier this month. They posted an expected goals total of just 0.1 in that defeat – the lowest by any team in a Premier League game this season.

Victory in Frank's first north London derby would be a huge statement, but history offers little encouragement. Spurs have won just one of their past 32 league visits to Arsenal.
