Many believe Robin van Persieâ€™s decision to join United instead of City from Arsenal last summer was the key to the Old Trafford club winning their 20th top-flight championship.
But Gunners boss Wenger said: â€śNo. The difference is that City have dropped off.
â€śRobin has made an impact, of course.
â€śBut the other teams are not as close this year â€” like Man City, who were always top last year. It was very tight last year. This year it was one-way traffic.â€ť
And Wenger claims United would have snatched the title last season, too, if Cityâ€™s final-day opponents QPR had not learned they were safe from relegation before conceding the dramatic Sergio Aguero goal.
Wenger said: â€śUnited lost only on goal difference and if QPR did not know that they were safe, they would have won.
â€śQPR knew they were safe in added time. When you know you are safe, you only fight for it for so long.â€ť
