Álvaro Arbeloa got off to a dismal start as the new coach of Real Madrid, seeing his team lose to second-division club Albacete 3-2 and drop out of the Copa del Rey in the round of 16 on Wednesday.

Jefté Betancor scored the game-winning goal four minutes into stoppage time to send Albacete to the quarterfinals. Gonzalo García had also scored in added time for Madrid to even the match at 2-2.

Madrid struggled from the start in the debut of Arbeloa, the club's former B-team coach who on Monday was picked to replace Xabi Alonso following a tumultuous eight-month stint at the helm.
