Goalkeeper Roy Carroll believes that his former side Manchester United displayed no hunger during their Champions League encounter with Olympiacos.

Carroll, who is back-up stopper for the Greek outfit, watched from the sidelines as Olympiacos opened up a 2-0 first-leg advantage against the Premier League champions, and the Northern Ireland international has claimed that standards have dropped since the departure of Sir Alex Ferguson.

The 36-year-old told Sky Sports News: "We have watched a lot of Premier League games this season and knew that United had not been performing. On the night when I was watching it live from the stands, I've never seen a Manchester United team like it.

"They've got good players but they had no hunger, no fight in the team, so it was a shock in that way but not a shock the way that we played. The goals we got were well deserved.

"They might have slacked off since Sir Alex left, it's football. People have their routines. You can't do that in the Premier League. It's a big league with top and bottom teams fighting for points and you have to be prepared every game."

Carroll made 72 appearances for United during a four-year spell at Old Trafford between 2001 and 2005.
