Korean star Park Ji-Sung believes back-to-back 5-0 wins by Manchester United can spark a ramped-up Premier League title charge. Park was on target after just eight minutes in Monday\'s 5-0 rout of Wigan as United went level on points with Manchester City at the top of the table for just his second goal of the season. \"It\'s our aim to be at the front. We always try to perform in this period of the season and we\'re just trying to make our performance higher,\" Park told manutd.com. \"We\'re still only halfway through the season and we will continue to press City. \"Quite a few players changed [against Wigan] compared to the last game, but we still kept up the same performance as we did against Fulham. It\'s good for the team and it proves that our squad is strong.\"
