The 28-year-old is frustrated with the lack of chances at Old Trafford with David de Gea proving difficult to uproot as the No. 1 following a string of impressive performances
The 28-year-old has made just one appearance since December and, after De Gea reiterated his desire to remain at the club despite reported interest from Barcelona, the Dane has admitted to being anxious over his future.
"For me at the moment it's not easy deal being on the bench when the team is performing as well as we do,” Lindegaard told reporters.
"And, of course, when David is also performing as well as he does and has been doing in the last couple of months.

"That's how football players are. It's a genetic thing in us - we live for the thrill of playing and the adrenaline you get when you step out on the pitch.
"With my best spell in my time at United so far I was on a good run. I performed, the team performed, the club performed... and then I ran into an unlikely injury.
"But that's how life is as a footballer - sometimes you get injured."
United sit atop the Premier League with a 15 point lead over closest rivals Manchester City and, although he has not featured prominently, Lindegaard says he is pleased to see his team-mates performing so well.
"I always say that clean sheets for a goalkeeper are like what goals are for a striker - it builds up your confidence," he added.
"It's already been a long season and, with a little bit of thinking back, you remember the times when people were thinking that United were leaking goals on another level.
"But we've done the best the club has ever done at this stage of the season. I think it paints a pretty good picture.
"I do think it is very difficult for Manchester United to exceed what is expected of us - we're expected to win every tournament we participate in, every game and not just to do it, but to do it in style.
"We're doing well and we do as we should do.
"My pride on joining United was massive. United has been a lifelong dream for me, since I was a small boy.
"I always watched Peter Schmeichel, Ole Gunnar Solskjaer, Eric Cantona and all the big stars on TV, so it was a life-long dream come true to join the club."
