Werder Bremen coach Thomas Schaaf believes his side gifted too many opportunities to Inter in the 4-0 loss at San Siro.
Schaaf saw his men improve in the second half, but the match was already out of their reach by that stage.
"We know that both [Samuel] Eto'o and [Wesley] Sneijder are great players and very dangerous," Schaaf told the Associated Press after the match. "I don't know if it was their birthdays today but we gave them too many presents.
"In the second half, our concentration was better and we changed our system a little bit but we didn't manage to give a reply."
