United lost the game 1-0 but Fergie is thinking positive despite defeat in the Champions League.
Ferguson told MUTV: “I’m disappointed, of course. But it was an opportunity to play some younger players and I’m not disappointed in them.
“Gabriel Obertan is 20, Danny Welbeck is 19 tomorrow, Federico Macheda is 18…
“They all showed potential and playing in these games gives them incentive to improve themselves.
“They know they’ll get that opportunity at this club. The club’s history is based on producing young players who can excite and these players can all excite.”
