is furious Manchester City risk missing out on Arsenal rebel Robin van Persie.
The Sun says the manager has become increasingly annoyed with football administration officer Brian Marwood for not securing Arsenal’s Dutch star.
Mancini was hoping to have signed Van Persie ahead of the club’s tour of China, with City due to play Arsenal in Beijing on Friday.
But the Etihad manager has been told that before a deal for Van Persie can be completed, he will first have to reduce the club’s wage bill by offloading at least one of Edin Dzeko, Emmanuel Adebayor or Carlos Tevez.
City have so far offered £15million — the highest bid so far — yet Arsenal insist they will not listen to offers below £20m as Manchester United, Paris St Germain and Juventus are also interested.
