Bebe's late effort salvaged a 1-1 draw after Kagawa had spurned a glorious chance to open his goal account. However, the Japan international impressed before Powell displayed neat skill as a substitute and was unlucky not to score before the injury-time equaliser.
"It was a competitive game," the manager told MUTV. "They caused us a few problems and we decided to make changes and bring on the younger players.
"Shinji was very good. He's an intelligent footballer, quick and has his head up all the time. He knows when a pass has to be made and I'm pleased. Nick Powell is a talented boy. He missed some training and 30 minutes was just stretching him a bit in terms of sharpness but the boy is a very good talent.
"We showed a reaction to losing the goal. We increased the pace in our game and could maybe have got a winner. It was a satisfying performance, a competitive game and a great atmosphere. Now we've got 16 hours' travel [to Shanghai] and we need to recover from that first of all."
