Arsenal boss Mikel Arteta admitted that Thomas Partey suffered a recurrence of his thigh injury before Tottenham’s second goal as Arsenal were beaten 2-0 in the north London derby.
Harry Kane and Heung-min Son put the Gunners to the sword with first-half strikes to return to the top of the Premier League.
And Arteta was left frustrated again as his team have now managed just one win in their last Premier League games.
He said: “We need to score goals. It’s unsustainable. We need to put the goals in the net urgently.
“Thomas was in a lot of pain. It is in the same area. I was trying to push him because I don’t think he realised the gravity of the situation.
“I saw a team full of passion, dominating the team and creating chances but in the end it is about the end product and that is why they are top of the table. I think we had 44 crosses.”
Jose Mourinho hailed his Kane and Son double act as “world class” after watching his side take north London bragging rights.
Kane became king of the derby, scoring his 11th goal, which is more than any other player in the history of this fixture – and set up Son with his tenth assist of the season.
Tottenham boss Mourinho said: “They are world class. They work together brilliantly for each other and also for the team.

“Of course we are very happy. We controlled the game by being defensively solid. Sonny and Harry, their finishing was amazing.
“Harry Kane clearing balls in the box, Sonny for the first 60 minutes as a winger and then a second striker – it is not just about scoring goals and being world class players.
“It is about being great guys and doing your best for the team.”
“We grew up. I can imagine lots of people can imagine three matches in a row – against Manchester City, Chelsea and Arsenal – would be a moment for us to drop points and go back to ‘normality’ but we didn’t go back to ‘normality’” said Mourinho.
Kane added: “Fantastic. Exactly what we set out for. The second half was a bit of a grind – they didn’t create too many clear cut chances.
“It’s a season where we’re all pulling in the right direction. We’re all defending and tackling.
“I’m happy to do it and win games and that’s most important thing. But it’s one game at a time – it’s been a tough period, but a result like this can only help us.”
