Sir Alex Ferguson pleased with Man Utd defensive display

Manchester United boss Sir Alex Ferguson says he is happy to just "keep on the coattails" of local rivals Manchester City after his side's 2-1 win over Arsenal at the Emirates keeps them three points behind the Premier League leaders.

Ferguson is full of praise for the performance of his defenders, and reserves special mention for in-form winger Antonio Valencia, who scored United's opener and set up Danny Welbeck's winner.
