Arsenal manager Arsène Wenger prepared to admit defeat over Robin van Persie and start auction process Manchester United, City and Juventus have all had bids turned down for the 28-year-old in the last few days, falling well short of Wenger's minimum £20m valuation, but Arsenal are bracing themselves for further offers early next week. And Wenger insists he will act in the best interests of his club as he attempts to resolve the matter before the start of the Premier League campaign. Wenger could demand up to £30 million for van Persie, and will use the transfer funds to strengthen his squad after already signing Lukas Podolski and Olivier Giroud. Atletico Bilbao's Fernando Llorente and Malaga's Santiago Cazorla are both believed to be targets. Arsenal arrived in Malaysia yesterday evening but van Persie, who has only completed four days of training after returning from extended leave after appearing at Euro 2012, will remain at home to work on his fitness. It is understood the captain's attitude has been faultless since his return and Wenger believes it will stay that way, despite the uncertainty surrounding his future. "As long as you are at the Club you give your best for the Club and that is the only pride you can have as a football player and as a manager," he said. Van Persie has one year left on his Arsenal contract and won both the Professional Footballers' Association and Football Writers' Association player of the year prizes last season.
