Manchester United boss Sir Alex Ferguson admits he was unhappy with his players after their 2-0 defeat of Inter Milan.

When Nemanja Vidic headed the Red Devils in front after just four minutes, Ferguson thought he was in for a night to remember.

Instead, it was nearly one to forget as United's play deteriorated, with the crossbar and then half-time coming to their rescue before Cristiano Ronaldo sealed victory with a second goal just after the restart.

"It was a long European night," sighed Ferguson.

"I didn't know if it was a game of football or a game of suicide.

"We started off very well and once we scored the first goal I thought we would go on and kill them.

"But then we opened the door for them with too many flicks, backheels and passes into space and were lucky to be in front at half-time."
