Ryan Giggs believes Robin van Persie’s world-class goalscoring talent will prove the key to Manchester United regaining the Premier League title. United’s reign as English champions was ended in agonising fashion last season as local rivals Manchester City pipped them to the title on goal difference on the final day. But United manager Sir Alex Ferguson reacted to that blow by paying Arsenal £24 million to sign Dutch forward van Persie in a bid to ensure a lack of goals wouldn’t be a problem again this season. Van Persie, who scored 37 goals in all competitions for Arsenal last term, has made a superb start to life with his new club, scoring four times in three appearances, including a hat-trick against Southampton last weekend. And veteran United midfielder Giggs is convinced van Persie’s presence is going to end up being the decisive factor in the title battle. “We lost it on goal difference, so hopefully the goals that he’s bringing, if it does come down to goal difference, then we’ll have the upper hand this time,” Giggs told Sky Sports News on Sunday.
