Kevin-Prince Boateng was delighted to make his Barcelona debut - despite losing at Sevilla in last night's Copa del Rey clash.
Barca lost 2-0 in the first-leg of the quarterfinal tie.
"Debuting with Barça has been a very special feeling, but I am angry about the result," said Boateng.
"It's very difficult to give the best level after a single training session, but I feel good and want to help the team.
"To have my first minutes as a Blaugrana, I feel happy.
"We have missed the last pass, but fortunately we have this week ahead to improve aspects and try to turn around the tie."
