Wenger also believes that the players are now making up for the disappointments of recent seasons.
Arsenal have finished runners-up to United in each of the last three seasons and were beaten by Liverpool-in last year's FA Cup Final. He said: "For a long time the team have had a special spirit and mental strength and I feel that every day.
"But they know it is not done. They are very happy, but will keep concentrating. There is a team spirit among the players after the frustrations of the last two to three years, and they said 'we want to be first this time'.
"They are confident after the results have come one after another, but they want to keep focused and win the title."
