Casemiro has admitted that Manchester United's form this season has caused him to suffer sleepless nights and added that the club need to adopt a "day to day" mentality and not get distracted by the race for the title or Champions League places.

United have been unable to build on their third place finish last season and are sixth on the table with 49 points. They are 11 points behind fourth-placed Tottenham and a mammoth 22 points behind leaders Arsenal.

"It's difficult. This is the point that bothers me most about not fighting for titles," Casemiro told ESPN Brazil after Sunday's clash with Liverpool.

"Being 20 points behind first place. Sometimes, I can't even sleep to try to think about doing something different. It's reality. There's no point in thinking about title or Champions League places, we need to think about today's games."

"We need to think about the day to day, we had the opportunity to score nine points in the last few games and we scored two. We were upset. We have to think game by game and focus on the next match, against Bournemouth."

Erik ten Hag's side have dropped seven points from winning positions within eight days after stoppage time collapses against Brentford and Chelsea, followed by the 2-2 draw against Liverpool on Sunday.

"The game [vs. Liverpool] was very fast-paced and well played. A classic. We were playing against one of the leaders of the competition and who is going through a good moment. We responded well," Casemiro said.

"Both teams had opportunities. The game was good. At home we are strong, but we played against a great team. We have to think about the next match."
