Manchester United striker Javier Hernandez believes their victory over Chelsea on Sunday could be decisive in the race for the Premier League title.
Hernandez scored a controversial winner 15 minutes from time at Stamford Bridge as United claimed a 3-2 win - their first top-flight victory at Chelsea for 10 years.
The victory extended United's winning run to five matches and cut Chelsea's lead at the top of the Premier League table to just one point.
Given Chelsea's early season form and the performances of summer signings such as Eden Hazard and Oscar, Hernandez believes the significance of United's win should not be underestimated.
"This game could have changed the title," the Mexican said. "That's why it was important we didn't allow them to get ahead.
"It was vital to get the three points at a very tough place. We are in there in the fight to win (the Premier League)."
Hernandez was in an offside position when he turned in the winner for United but he was unconcerned by the furore that followed.
"I don't' care... the referee counted it," the 24-year-old said. "When Robin (van Persie) shot and (Petr) Cech made a great save I went for the rebound and the ball went to Rafael.
"The first thing was to get along the line of defenders because I thought that was where the ball was going to go. Thankfully I reacted well to it."
It was Hernandez's third goal in his last two games for United but the striker insisted the result, rather than his goalscoring record, was the most pleasing aspect of the day.
"It doesn't matter who scores the goals," he said. "It has been a good week for me. But the most important thing for me is to have the minutes on the pitch and help the team."
