Manchester United completed their swoop for Arsenal striker Robin van Persie on Friday after the Dutch star passed a medical and agreed personal terms on a four-year contract. Van Persie\'s transfer, which is believed to have cost United around £24 million ($37 million) has been completed in time for the forward to make his debut in his new team\'s opening Premier League game of the season at Everton on Monday. The 29-year-old\'s signing is a significant coup for United boss Sir Alex Ferguson after he persuaded van Persie to snub an offer from Premier League champions Manchester City in a favour of a move to Old Trafford. \"Robin van Persie has completed his medical, agreed personal terms and signed for Manchester United on a four-year contract until June 2016,\" a statement on United\'s website confirmed.
