United have managed to beat Newcastle and West Ham while only managing a draw at Fulham.
“We’re pleased to have won two of our three games, but we know we can still improve,” Park told ManUtd.kr.
“We are experienced enough to know that as we get more games under our belt, our qualities will shine through.
“It has been a good start for Chelsea but we are not worried about that as it is a very long season.
“Each team has their ups and downs and the real test for Chelsea will come when things are not going so well for them.”
