Al Sadd boss Xavi was left feeling angry with his players after they suffered a heavy 6-2 defeat to ES Tunis at the Club World Cup on Tuesday.
The Qatar champions were dismantled by a hat-trick from forward Hamdou Elhouni, producing what their head coach described as a "very disappointing" performance at Doha's Khalifa International Stadium in the fifth-place play-off.
Al Sadd did play the majority of the contest with 10 men after defender Abdelkarim Hassan was deemed to have blocked a goal-bound shot with his hand, leading to a straight red card.
