Man United: Hernandez & Rooney will get 20 goals apiece - Ferguson<br /><br />Sir Alex Ferguson believes Manchester United have enough attacking firepower to avoid losing successive Premier League titles on goal difference.<br />And he reckons Javier Hernandez and Wayne Rooney will both score 20 goals plus - in addition to the contribution of current top-scorer Robin van Persie.<br />United lost the title last season to Manchester City's superior goals tally.<br /><br />Ferguson insists United have a balanced strike force, and said: "I don't expect us to lose on goal difference again."<br />Van Persie has scored 11 goals in 14 matches in all competitions since his summer move from Arsenal - but Ferguson believes United have not become over-dependant on him.<br />"I don't think it's a problem relying on Robin," he said.<br />"The way Javier has started this season, I'm certain he will get to 20 goals plus.<br />"Wazza will get there too, he'll get 20 goals plus I'm sure. It's a healthy combination we've got there."<br />Champions City scored 93 goals to United's 89 last season, while Roberto Mancini's men also conceded four fewer.<br />But Ferguson's side - who also have Danny Welbeck in a four-man strike force - have scored more than any other top-flight side this season - 26 goals in their opening 10 Premier League matches - with Van Persie netting eight.<br />The Premier League leaders, who have sealed qualification for the Champions League knockout stage with two group matches remaining, have won every game where the Dutchman has scored.<br />Van Persie, 29, was named on the bench for Wednesday's Champions League tie in Braga, where United trailed 1-0 before he was introduced to equalise and inspire a 3-1 victory.
