Ojo lasted for 57 minutes in the hybrid encounter as Kelechi Nwakali and Usman Mohammed's superb strikes failed to save the Super Eagles B from defeat.
However, the Sunshine Stars man insists they gave 'very good account' of themselves against Diego Simeone's men.
"It wasn't a bad game for us considering the fact that we only trained together twice," Ojo told Goal.
"You can't use such short preparation to play against one of the best team in the world and expect to win but I think generally we did well.
"I believe that we have a very good account of ourselves against one of the best club in Europe. They are a very good side I must confess and really gave us a tough time.
"Honestly, It was a wonderful opportunity for me and I'm very proud to be part of such a big game like this because I've gained more experience and also had great moments."
