Heung-min Son and Harry Kane scored two fine first half goals on the counter-attack before, with Arsenal much improved, Spurs were forced to defend throughout the second half.
After beating Manchester City, drawing at Chelsea and now rounding off that triple-header with victory over their rivals, Mourinho says his side “grew up”.
“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,” said Mourinho. “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’.
“We are there. I believe one more week at the top of the table unless Liverpool win by many.
“We were reading the game and making the changes to win it because 2-0 was in our hands against a great and difficult opponents but my boys did well today.
“I am very happy with the result and the performance but of course I want the team in the second half to play in a different way. In reality you don’t always do what you want to do because your opponent forces you in a different direction.”
