Manchester United boss David Moyes says he is not concerned about his future despite his team's struggles.
The Old Trafford club lie seventh in the Premier League table and trail Champions League rivals Olympiakos 2-0 going into Wednesday's second leg of their last-16 tie.
"My future has not changed one bit," said Moyes. "I have a great job.
"I have a six-year contract. This club does not work on short-term vision, it works on a long-term vision."
Moyes took over from Sir Alex Ferguson last summer but has struggled to continue the success his predecessor enjoyed in his 26 years in charge of the club.
Ferguson won 13 league titles and two Champions League trophies before retiring last year.
In defence of their top-flight title, United are currently 18 points off leaders Chelsea after being comfortably beaten 3-0 by fierce rivals Liverpool on Sunday.
Moyes says he continues to talk regularly with Ferguson, as well as United vice-chairman Ed Woodward, and says both men are "very supportive".
United are also 12 points off the top-four spot needed to qualify for next season's Champions League.
Their best chance of booking a place in European football's top club competition appears to be by winning this year's tournament.
However, they will have to overturn a 2-0 deficit against Olympiakos, having won just six of their 14 league games at home this season.
Moyes still thinks victory is possible.
"It's not something that happens a lot, but it's something we believe we have to make happen," he said. "I've got belief in the players."
He added: "The fans have seen some defeats they would not have expected and they have stuck with the team.
"They have seen great success and will see great success in the future. This club is the biggest in the world and it will rise again."
