Arsenal will demand more for striker

Arsenal will only accept anything upwards of £20m for wantaway striker Robin van Persie, but will demand an extra £5m if Manchester United are to bid for the 29-year-old.

Van Persie has been linked with a move away from the Gunners after turning down a new long-term deal with the North London side.

United are currently leading the way for the front-man, but Arsenal are set to demand top dollar for their captain.
