Park Ji-sung is confident Manchester United can win the Premier League and UEFA Champions League again despite a shaky start to the season.
The Red Devils are currently in eighth place in the Premier League with one game in hand and face tricky opponents this weekend when West Bromwich Albion visit Old Trafford.
Park, who was influential in South Korea's 4-1 thrashing of UAE in midweek, reassured fans that United will improve.
"The team had a poor start last season too. We are not playing to our full potential yet," Park told the Korean press.
"In the end, we came away with the Premier League title and the Champions League.
"So there's nothing to be concerned about. I don't think we will have problems repeating last year's achievements."
