Ji-Sung Park sees no reason why Manchester United cannot secure domestic and European success this season.
The Korean winger has recently returned to the first-team fold at Old Trafford following a lengthy spell on the sidelines and is determined to play his part in the Red Devils' quest for glory at home and abroad.
United go into the second leg of their UEFA Champions League quarter-final with Roma on Wednesday already 2-0 up from the first meeting in Italy last week.
Strong favourites to progress to the last four in that competition, United also lead the way in the Premier League, three points clear of nearest challengers Chelsea with just five games remaining.
With Sir Alex Ferguson making no secret of his desire to claim a second European crown, Park remains confident that the Red Devils can maintain their challenge on two fronts heading into a crucial stage of the season.
"We can win the league as well," he said.
"We can do the double."
The South Korean international also feels that the strength in depth now available to Ferguson will help United to cope with the demands of a fixture pile-up towards the end of the current campaign.
"In a couple of matches we've changed the team around but still managed to get good results," Park said.
