Former Manchester United and current Olympiakos goalkeeper Roy Carroll, reckons that Manchester United's season could get worse on Tuesday night when they face Olympiakos in the Champions League.
United travel to Greece to face the league leaders in the last 16 of the Champions League, and Carroll, who was at Old Trafford for four years, says his team are determined to cause an upset and are encouraged by United's poor season.
Speaking to the Daily Mirror, the goalkeeper said: "That gives us belief; that even the best teams - like United - can be beaten. That's the way we're looking at it, with United not in the best of form at the moment.
"It's important for us to get something from the first leg to take to Old Trafford. We must get some sort of result at home first."
The Northern Irish international says that the departure of Sir Alex Ferguson "was always going to be tough".
Manchester United currently sit sixth in the Premier League, 11 points behind Liverpool who lie in the fourth Champions League place, and face the possibility of not qualifying for next season's competition.
The 36-year-old has fallen out of favour at Olympiakos but hopes to extend his contract with the Greek team when his contract expires.
