The game at Old Trafford on Wednesday evening ended goalless but the United boss said he could take a lot of positives from the game.
"I think we played some good football," Fergie told MUTV.
"The lads expressed themselves and enjoyed themselves and played with a great deal of commitment.
"Considering three or four players were playing their first real game of the season I think we can take heart from that performance.
"We were unlucky not to win it."
"Carlos Tevez had a shot knocked off the line and Jonny Evans hit the inside of the post.
"I think Cristiano would have scored with his header had Carlos Tevez not got in his eyeline, which distracted him a bit.
"But I'm pleased with the performance. I think the boys showed great commitment."
"Ji-sung Park was absolutely fantastic tonight, I was very pleased with his performance, and aside from the game in Monaco, it was Nani's first real start for us this season. I thought he did very well."
