Sunderland boss Gus Poyet says some of his team may have played themselves out of places in the starting XI for next weekend's Capital One Cup final after a poor display at Arsenal.
The Black Cats will play Manchester City at Wembley next Sunday but did not enjoy a happy warm-up at the Emirates, conceding early on, falling further behind after a shocking back pass from Santiago Vergini, and eventually losing 4-1.
And Poyet said: "We were very, very poor technically.
"We did not give good angles and we were not brave enough as a team to pass the ball. If you only come here to defend, sooner or later you are going to concede.
"Some people concede after 70 and lose the game anyway. We came today and conceded after a few minutes - then it becomes difficult.
"After that, you cannot make mistakes, but we made a big one, and then it was a very long and difficult afternoon.
"Let's not forget it was Arsenal we were playing away from home and they have got quality.
"You need to be smart enough to slow down the game and organise. You have to be patient and press the ball, but we didn't."
And Poyet admitted that he is now unsure about his line-up for the Wembley showpiece next week.
"This was a perfect preparation because of the opposition, the pitch and the stadium," he said. "But only doubts I have got in my head now, plenty of doubts.
"There are maybe players who are not expecting to play, who will play next week.
"Apart from Manchester United in the cup semi-final, and Everton, we haven't played many of the top teams away from home. Today was the first time and it didn't look very good. We have to make sure we do better."
Asked if he will now turn his thoughts to the date with Man City, he added: "I'm the person responsible, so I need to reflect on this tonight first and analyse what I did wrong."
