Sunderland boss David Moyes has criticised his team's back four for their performance in the 3-0 defeat to Everton on Monday night.
The two teams were level entering the final 30 minutes of the Premier League clash at the Stadium of Light, but Romelu Lukaku hit an 11-minute hat-trick to secure all the points for the Toffees in comfortable fashion.
Moyes has said that he was pleased with the first-half performance, but 'could not believe' that Lukaku had so much space inside the Sunderland box in the second period.
"We were really poor in the second half, but I thought, in the first half, we showed some good things. We had one or two opportunities ourselves," he told Sky Sports News.
"But we weren't in the right positions to defend crosses in the second half. For two of the goals from crosses, I couldn't believe we didn't have defenders in the middle of the goal, especially against Lukaku. We're putting together a new team, it will take time. But I was really disappointed with the last 30 minutes especially.
"There have been a couple of games where we've been right in it right at the end, but the minute we lost a goal tonight, we never looked like getting back into it. I thought we gave them away really cheaply, we didn't do basic defending and we got punished."
Sunderland have only collected one point from their four league games this season, and as a result currently sit 19th in the table ahead of this weekend's trip to Tottenham Hotspur.
