Arsenal may report Manchester City for tapping up Robin van Persie. The Sun says the club are convinced that Van Persie's agent Kees Vos has already been in touch with the Premier League champions.

Manager Arsene Wenger and chief executive Ivan Gazidis called Vos yesterday to express their fury at how RVP announced he would leave on Twitter.

No club has invoked the Prem's Section K rule on illegal approaches since Chelsea were fined £300,000 for their part in Ashley Cole's move from Arsenal in 2005. City are adamant they have done nothing wrong.
