Only three games into their Champions League campaign and Manchester United are facing the threat of early elimination.
In their first two fixtures, United have lost 3-2 at Bayern Munich and 3-2 at home against Galatasaray.
Now, the Red Devils have to beat FC Copenhagen if they want to qualify for the Champions League knockout rounds
United sit bottom of Group A ahead of the match at Old Trafford.
FC Copenhagen, champions of Denmark, visit Old Trafford on Tuesday and Ten Hag has said his team must win.
After losing six of their first 10 games of the season, United have won back-to-back matches with narrow victories over Brentford and Sheffield United.
Ten Hag’s team are looking to win three games in a row for the first time since May.
“If you lose the first two games, you have to win,” Ten Hag told a news conference on Monday.
Ten Hag is expecting an emotional atmosphere at Old Trafford in United’s first home game since the announcement of Sir Bobby Charlton’s death, aged 86, on Saturday.
“It is always special, every night at Old Trafford, the fans are always so behind us,” Ten Hag added. “Remember the last home game against Brentford, even when the game is not going in our direction, they stayed behind us in difficult moments.
“In moments of adversity the fans are still with us and fighting. Definitely tomorrow, the passing of Sir Bobby Charlton — their hero, the legend — it will be more emotional.
“He is in front of Old Trafford with Denis Law and George Best. He is always with us and they are always a huge inspiration for us every day in every game.”
