Stoke 0-2 Man Utd: Ferguson on 'perfect' Van Persie penalty

Manchester United boss Sir Alex Ferguson praises Robin van Persie's "perfect penalty" following their 2-0 Premier League win at Stoke.

Michael Carrick put United ahead early on before van Persie's second-half spot kick ended his run of 10 games without a goal.

United are now 15 points clear of nearest challengers Manchester City and need seven points to secure their 20th league title.
